This update adds a clickable button to the puzzle screen that toggles on or off the option to point out rows and columns that can be worked on. It also adds equivalent keyboard and gamepad inputs to do the same, with the keyboard input defaulting to the quote key and the gamepad input unassigned by default, since the other inputs are used already. The update also fixes an issue with puzzle sizing and placement that would occur if extra row and column info was enabled and the resolution was set to an ultra-tall one, meaning absolutely no one encountered the problem anyway, but whatever.

Added the ability to change the location of the "Nonozle User Puzzles" and "Nonozle User Themes" folders, which by default are created in the Documents directory on Windows and in the home directory on Linux. To do this, create a .txt file called "export_location.txt" in the base save file folder ("C:\Users\[user]\AppData\Local\Nonozle" on Windows, "~/.local/share/Nonozle" on Linux), not any sub-directories of it. Have the text file only contain the path to the new directory. If the specified directory doesn't exist, then the text file will be ignored. This won't move or delete the already existing folders and their files, if any. You'll have to do that manually.

The very first puzzle (A-1) in the Food and Drink DLC puzzle pack has been changed to make it look more like the intended subject of the puzzle. If you already completed the puzzle, it will still be shown as completed, but if the puzzle was mid-progress, it'll likely have to be redone (my apologies), though the change to the puzzle may not take effect until Steam is restarted. Edit: Also, the [spoiler]Eggs[/spoiler] 15x15 puzzle has been redone and made much harder (from 14 pass counts to 36 pass counts). The 15x15 puzzles in the Food and Drink pack have been rearranged accordingly.

Looking for more puzzles to play? This new DLC combo pack contains 100 new puzzles, ranging in size from 15x15 to 30x30. There are two packs included: a food and drink themed one and an unthemed (miscellaneous) one. Each has 50 puzzles. Fair warning, the puzzles should overall be harder than the ones included in the original puzzle pack! https://store.steampowered.com/app/3077890/Nonozle__Food_and_Drink__Miscellaneous_Puzzle_Packs/

Nonozle's color theme system and theme editor have been totally reworked. Prior to this update, the game had three built-in themes and a hard limit of five custom themes that couldn't be renamed or shared. With 3.02.00, themes are now like puzzle packs: you can rename them, sign and export them, and add as many as you want.* The five existing custom themes will be imported into the new system on first startup. But the theme you had selected as your current theme prior to 3.02.00 will not be recalled because the method of saving and recalling which theme is the current one has been changed.

Twelve new included themes

Primary color differences

Theme select

Theme editor

Sharing themes

New color types, new color assignments

New color types

• "Button and credits background", which buttons and the credits screen now use as their background color instead of just using the "Background" type
• "Dots" color type, which page dots now use instead of the "Text" type they used before
• "Hint highlight" color type, which hint highlights now use instead of simply using the primary color with a lower opacity
  • Removed "Hint highlight opacity" as an option and concept in themes
• "Puzzle select button background" color type, which puzzle select buttons now use instead of using a variant of the primary color
  • As a result, puzzle select buttons now no longer change color slightly when selected
• Added "Selected square border" color type, which the selected square in a puzzle is now outlined with when the "Outline/border color" option under "Puzzle appearance" is set to "Themed"

Renamed color types

• Dropped "color" from the end of all color types
• "Main color" to "Primary"
• "Faded text color" to "Faded hint" to reflect its new singular purpose
• "Highlighted hint fade color" to "Faded hint (highlighted)"
• "Arrow and X button color" to "Arrow, X button, slider handle" to reflect its new use
• "Input color" to "Highlighted text" to reflect its varied uses
• "Five-line alt. color 1" to "Five-line alternate 1"
• "Five-line alt. color 2" to "Five-line alternate 2"

Color type reassignments

• The puzzle select button checkmark now uses "Primary" instead of "Puzzle title text"
• The slider UI element now uses "Border" for the bar and "Arrow, X button, slider handle" for the handle instead of using hard-coded grey colors that didn't change with the theme
• The outline around actionable row/column hints now uses "Text" instead of "Faded hint" for greater visibility
• The background color behind UI elements in the main menu now uses "Puzzle grid background" instead of "Background"
• "A game by HopefulToad" and the version number text now use the primary color instead of "Text"
• The icon box on the title screen now uses "Puzzle grid" instead of "Border", which is how it should have been in the first place
• The toggle square on toggle buttons now uses "Text" instead of "Primary" for maximum visibility regardless of the theme ("Text" will always be highly visible against "Button background" in a usable theme, but "Primary" might not be)
  • Additionally, the toggle no longer specifically changes color when it's disabled (other than the overall fade applied to the entire button)
• Checkmarks and signatures in the puzzle pack select screen and URLs in the credits now use "Highlighted text" (previously "Input") instead of the primary color to ensure visibility
• Disabled buttons now fade using a partially transparent "Background" rectangle overlaid over them rather than using "Faded hint"
• Percentage bar colors and appearance have been reworked; see "Other miscellaneous changes" below

New UI element: DropList

Puzzle layout changes

Bug fixes

• Fixed rumble bugs
  • Fixed UI-movement type rumble occurring in puzzle pack selection, pack editor, and virtual keyboard screens even when it was toggled off.
  • Removed an extra rumble on puzzle restart that shouldn't have been there
  • Added back in the big rumble on puzzle solve which was mistakenly missing
• Fixed a minor visual bug with the fade animation in tutorial puzzles that became more noticeable when I was trying out new themes.
• Fixed a bug where the puzzle title shown in the solved puzzle screen would not update when the puzzle was renamed (until the game was restarted)
• Fixed bugs where UI reconstruction and primary color changes were not propagating to exported (other user) puzzle packs that weren't currently loaded into the reusable puzzle select scenario
• Fixed a bug with the puzzle solved animation that was only visible when the background and puzzle grid background colors were different
• Fixed font index and scaling settings not changing when all settings are reset to their defaults
• Fixed a bug where having empty inputs in multiple control categories (universal controls + one or more others) would be considered a conflict due to empty being considered the same input as empty
• Fixed an issue where elements of the puzzle solved screen would pop into view instead of fading into view when the puzzle solved ripple was disabled
• Fixed a resolution change being triggered twice on startup when it didn't need to be
• Fixed tutorial puzzle hint highlights being drawn over the puzzle grid instead of behind it

Other miscellaneous changes

• "Extra 2," another puzzle track disabled by default, has been added into the game. It was a track I composed at the same time as the others but didn't initially include with the game.
• The game now remembers the most recent puzzle you had selected within a puzzle select scenario in-between sessions. For instance, if puzzle B-45 was the last selected puzzle in the original puzzle pack at the time you close the game, when you start the game again and go to the original puzzle pack, it will start with that puzzle selected still. The only exception to this is with puzzle packs by other users due to their dynamic nature. They will instead automatically navigate to the earliest as-yet-unsolved puzzle.
• The UI of the puzzle validation screen has been simplified. Instead of two separate buttons ("Skip solve animation" and "OK") where only one would be enabled at a time, there's now just one button that changes its text and function as neededit starts as "Skip solve animation" and changes to "OK" once you click it or once the animation has played out. Also, the back input now skips the solve animation and exits the validation screen, allowing you to intuitively mash either the select button or the back button when you're impatiently repeatedly tweaking a puzzle trying to get it to be solvable.
• A certain puzzle in the original puzzle pack has been renamed to "Ice Pops" because the prior name is actually trademarked and I'm scrupulous.
  • Once the DLC comes out, "Ice Pops" will have the honor of being the only puzzle title to be used twice among any of the puzzles I've published, though the two puzzles are not identical.
• Because the puzzle grid can now be closer to the bottom and right edges of the window/screen than before, it transpired that in certain cases the counting label would be partially off-screen. To rectify this, the counting label is now moved to the left side of the selected square when at the right edge of the puzzle and moved to the top side of the selected square when at the bottom of the puzzle.
• As mentioned under "New color types, new color assignments" above, a new option has been added to the "Border/outlined color" setting: "Themed." With this option, the selected square (and optional row/column outlines) will use the "Selected square border" color from the current theme. The other five options for that setting still do what they did before, but "Themed" is the new default and recommended option.
• The percentage bars representing music and sound effects volume and gamepad rumble intensity have been reworked visually. Previously, with the button inflation animation disabled, it was impossible to tell they were the currently selected button when full. To fix this, a buffer was added that surrounds the bar, so you can see the color of that buffer change when the button is selected versus when it's not. Mouse input involving the bar has thus been modified to account for the buffer. Additionally, the bar itself is now uses the "Selection" color type rather than a partially transparent "Primary." This addresses visibility issues with some of the new themes that weren't apparent with the original three built-in themes.
• All MultiOptionSelectors that contain only two options have been made non-wrapping for consistency. In fact, there are no longer any MultiOptionSelectors that wrap, because the only ones that used to wrap were two-option ones.
• All references to "visual theme" have been changed to "color theme" instead.
• Tutorial select buttons now ignore the puzzle transparency and solved puzzle border settings, displaying with the former and without the latter no matter what. It didn't really make sense to apply those settings to them in the first place.
• The default puzzle solved animation option has been changed to "Shuffle."
• The hint highlight on single-row tutorial puzzle examples has been removed as there's not much point in highlighting which row is being modified when there's only one row.
• The opacity of tutorial puzzle row/column highlights has been increased.
• The "Only aggregate ones" option is now disabled when hint aggregation itself is disabled.
• The positions of the music and sound effects volume bars have been swapped.
• The slider handle size is no longer determined by the number of units the slider has. Also, how the position of the slider handle is determined, including when using the mouse, has been modified.
• The number of disparate progress sections in the game's initial loading screen has been reduced to ten.

DLC puzzles out soon!

This update gives you greater control over the range of solver pass counts you want when generating a puzzle. For any given line-solvable puzzle, the solver takes a number of passes before completing the puzzle. This number is useful as a rough approximation of difficulty. Before this update, when generating a random puzzle, you would pick a percentile range that you wanted the random puzzle to fall within. Now you can specify the exact pass count range you want.
As shown in the screenshot above, you're presented with a graph representing the distribution of solvable puzzles by pass count for the selected puzzle size. You can select any range on the graph, and the readout will display the percentile range and what percentage of puzzles fall within the range you've selected. Keep in mind, the smaller the percentage of puzzles within the range, the longer it'll likely take to generate a puzzle within that range. If you select only the tail end where the outliers are, where only .0001% percent of puzzles fall, for larger puzzle sizes generating the puzzle could take days or even months! You also have the option of skipping selecting a pass count range and just going with the first solvable puzzle that's generated, regardless of its pass count. This is also the only option for 30x30 puzzles since generating a solvable 30x30 takes so long. To get the distribution of pass counts, I generated 10,000,000 solvable puzzles of each size, except for 25x25, which I only generated 1,000,000 for, and 30x30, which I didn't bother with because it would have taken months of 100% CPU usage to get a decent sample size. Prior to this update, the percentile ranges were based on smaller sample sizes, so they should be more accurate now. Also, when a random puzzle is generated, it now tells you its exact pass count and percentile range, and you have the option of seeing the same information for every puzzle in the puzzle select screens if you want. A full list of changes follows.

• Increased the pass count sample size for more accurate data. Prior to the update, percentile ranges were based on sample sizes of 1,000,000 (100,000 for 25x25). They have now been increased to ten times that size.
• Changed how the pass count data mentioned above is accessed by the game. Previously, I only stored the pass counts at specific percentile intervals, meaning that percentile ranges were limited in their accuracy and only pre-determined percentile ranges could be used when generating a puzzle. But now all of the statistical data is included, so percentile ranges that are shown are much more accurate and narrow, and any arbitrary range can be selected when generating a puzzle.
• Added a screen for selecting a specific pass count range prior to generating a random puzzle. The screen shows a graph with the distribution of pass counts for the given puzzle size, and by clicking/pressing and dragging on the graph, you can select the range you want. It will also tell you what percentage of random puzzles fall within the range you selected and the percentile values of the range. Additionally, the pass count range for each size is saved so that, when you exit the game and start it again, the same range will be selected as you left it.
• Changed the thread count to be saved so that it doesn't reset each time you start the game.
• When generating a random puzzle, the distribution data is now shown behind the live bar graph, so if you select a range where a very small percentage of puzzles is found in it, you can watch as the live graph gradually conforms to the curve of the pre-calculated data.
• The pass count (and percentile range for puzzles smaller than 30x30) of the randomly generated puzzle you'll play is shown once it's generated.
• By enabling the option at Settings > Appearance > Other appearance settings > Show pass count data in puzzle select, you can see a text readout telling you the pass count and percentile range, if applicable, of the currently selected puzzle in any of the puzzle select screens. If you have a lot of saved random puzzles, the initial startup after this update might take a while, because I neglected to save the pass count of saved puzzles prior to this update, so they have to be recalculated the first time you start the game after this update.
• The warning about discarding the currently paused random puzzle has been moved and reworded.
• Added a button to generate a random puzzle without specifying a pass count range, if you're not particular. This is the only option for 30x30 puzzles.
• Changed the title of the random generation window so that it lists the pass count range instead of the percentile range.
• Moved the label showing the count of the tallest bar to the right edge of the bar graph so that it doesn't overlap the bars.
• Fixed system memory that is no longer in use after generating a puzzle not being freed up.
• Fixed a crash that could occur if you have a 64-or-more-thread processor (look at you!) and selected more than 31 threads when generating a random puzzle. Everyone is now limited to 31 threads maximum, and less if your CPU has less threads.
• Fixed the "check if correct" option giving erroneous reports after using undo.
• Fixed random puzzle generation window's title not having the correct font size.
• Fixed a few issues with transition animations.
• Reworded some info pop-up text and probably some other things.

Fixed a crash that could occur when a puzzle is filled in incorrectly when using the original hint fading method. This bug was introduced in 3.00.00 but escaped my notice.

This patch adds a new button on the puzzle screen that you can click that will bring up a dialog telling you whether or not the puzzle as it is currently filled in is correct. It also adds a keyboard and gamepad input to do the same. This saves time if you just want a quick sanity check but normally keep the option to warn if the puzzle is incorrect turned off.

This is a big update, with many changes big and small. The headlining feature of the update is Workshop integration, allowing you to upload and share puzzles and packs of puzzles with other Steam users. Other changes include, but are not limited to, the addition of optional hint aggregation, the overhauling of the puzzle editor, and the retconning of all built-in puzzles to be line solvable. With such a big update, there's bound to be a few bugs that I missed, so please report any that you find, or any crashes you experience, on the game's forum so that I can fix them as quickly as I can. Thanks! An extensive explanation of changes that have been made follows.

• Changed how puzzles are saved to binary (they save their solver pass count now)
• Changed the sound effect that plays when moving the slider in the expanded color picker. The same sound effect also plays when scrolling in other contexts, and when the puzzle grid lines are sliding out of view during the puzzle solved animation.

What's next for Nonozle?

Good news, Linux/Steam Deck users! The game now has a native build for Linux. This should mean improved performance compared to playing the Windows version on Linux through Proton. Thanks to Steam Auto-Cloud, if you switch over to the native version, your save files should be synced to the new save location and things should just work.

However...

Font options are here! Along with the original font, there's now a new font with similar metrics to the original but with curves instead of blocky corners. There's also an updated version of the original font with some tweaks and more consistency, but the unmodified original font is still selectable if you prefer it. That makes a total of three fonts, with the potential for more being added later. This update also makes a number of changes to the game's overall appearance, some slight and some significant. A full list of the changes made can be found below.

New fonts

• An option has been added to change the font in use. It can be found at (Settings > Appearance > Font).
• A new font, called "curve font", has been added to the game as an option.
• A modified version of the original font, listed as "block font (new)", has been added to the game.
• A new option allows you to choose whether or not you want to always use a scaled higher resolution font.
  • Each font has a high resolution version, which is scaled up or down to match the game's current resolution settings. At lower game resolutions, though, smaller custom versions of the fonts are used instead, unless this option is enabled.
• Fonts now scale dynamically rather than using hard-coded scaling intervals.
• Kerning is now only done between letters, with punctuation always being excluded. Previously, certain punctionation like / was subject to the built-in auto font kerning, but things like URLs look better without it.

Puzzle hints changes

• Puzzle hints are now evenly spaced for both rows and columns.
• Puzzle hints are now automatically sized to closely match the size of the puzzle squares.
• Puzzle hint highlights are now consistently sized to match the puzzle squares.

Other appearance changes

• Improved puzzle grid sizing and placement.
• Improved puzzle select button sizing and placement.
  • The button size is now more consistent between resolutions, and the buttons are now centered vertically in the screen/window.
• Improved overall UI scaling. Specifically, UI elements are now always scaled relative to the size of the text, providing a more consistent experience across resolutions.
• Improved tutorial page UI element sizing and placement.
• Moved optional extra puzzle column and row info to be above the "Fill placeholders" button in the lower left corner of the puzzle screen, leaving more room for the puzzle itself.
• Changed the loading screen.
  • A small image of the frog from my logo now spins in the lower right corner.
  • Instead of a progress bar, the game's title text gradually fills in with full color as loading progresses.
• Moved the checkmarks that optionally mark which puzzles have been solved to the upper right corner of the puzzle select buttons. This leaves more room for the titles of the puzzles.
• Added a third type of main menu button arrangement to better match ultra-tall resolutions, which almost certainly no one uses, but whatever.
• Changed how the size of toggle and color swatch boxes is determined for better consistency.
• Changed toggle and color swatch boxes to no longer move back and forth when the containing button is selected and hovering.
• Fixed various issues with overlapping or cut off UI elements at various resolutions.
• Fixed the "User puzzles" text on the main menu exceeding the boundaries of the button at certain resolutions.
• Fixed sound effect, playlist, and theme editor buttons not downsizing correctly at certain resolutions when they needed to.
• Changed the game title and icon to be more consistent across both the title screen in-game and in various other places, such as Steam store and library images.

Settings changes

• Changed "Options" to "Settings" for consistency.
• Rearranged display, appearance, and puzzle appearance settings.
• Added a new sub-menu of "Other appearance options" to make room for the new font settings, with a number of the appearance options having been moved there.
• Added a link to puzzle appearance settings to the appearance menu. It can now be accessed both by (Settings > Puzzle > Puzzle appearance) and (Settings > Appearance > Puzzle appearance).
• Changed other five-line related options to be greyed out when five lines themselves are disabled.

Other changes

• Removed the fade in effect of the intro HopefulToad logo screen, and changed the fade out effect to be skipped when the intro screen is skipped to make getting to the main menu faster.
• Removed unused lines of text from the game.
• Replaced references to "the below example" in one of the tutorials with "this example," since the examples in question are actually above the text, not below it.
• Changed some info pop-up text for clarity and consistency.
• Changed text in dialogs and in tutorials to auto-wrap instead of using hard-coded newline locations.
• Ensured that the most recently selected puzzle button will always be selected upon re-entering a puzzle select scenario, no matter what settings have been changed mid-puzzle.
• Fixed an issue where, at the main menu at certain resolutions, if the settings menu was closed via mouse and the mouse wasn't moved, clicking wouldn't change the currently selected main menu button to the one the mouse was hovering over.

Craving more challenge? Try out the new "brainracking mode" option.

• Hint fading
• Xs and placeholders
• Undo and redo
• Counting
• All puzzle assists

The random puzzle generation process has been overhauled.

• The size of puzzle being generated
• The desired difficulty percentile range
• The elapsed time
• An estimate for the time remaining.
  • This estimate is based on the average time the generator has taken to generate a solvable puzzle and the estimated number of solvable puzzles that need to be generated before one that falls within the desired difficulty range is expected. For instance, if the percentile range is [99.99 - 99.999%], then only 0.009% of solvable puzzles fall within that range. Thus, on average, about 11,111 solvable puzzles will need to be generated before one of them falls within that range. If the generator has been running for 40 seconds and has generated 1000 solvable puzzles in the meantime, that's 25 per second. If we expect to need to generate around 11,111 before we get one in that range, then it should take about 404 more seconds to generate the desired puzzle.
  • The time is only an estimate to give you an idea of how long you might have to wait. You could get lucky and get the desired puzzle sooner than expected, or get unlucky and have it take longer than expected.
• The total number of puzzles generated
• The total number of solvable puzzles generated (and the percentage of all generated puzzles that are solvable)
• The total number of unsolvable puzzles generated (and the corresponding percentage)
• The number of solvable puzzles that have been generated so far that fall within each of the selectable difficulty ranges

Other changes

• Added the characters {|}~ to the game font. The font now covers the entire printable range of ASCII characters. This was done because the URL of the aforementioned paper has the ~ character in it, and I included a mention of the paper and its URL in the game credits.
• Randomly generated puzzles now have (R) preceding the date and time in their title so that they can be distinguished from regular user puzzles.
• Fixed a bug caused by turning off actionable hints, working on the puzzle, and then turning actionable hints back on (with advanced hint fading disabled).
• Fixed a bug where page change arrows wouldn't be properly visible if you had more than a page worth of user puzzles of a certain size but no user puzzles of any other size.

• Fixed random puzzles not resizing correctly when the resolution is changed.
• Fixed some puzzle UI element sizing and overlap issues.
• Changed hint fading to default to the original method of hint fading. Advanced hint fading must now be enabled manually.
• Fixed random puzzles not showing the size of the puzzle when the option to show the number and size of the puzzle is enabled.
• Changed how the random puzzle generator menu works to better communicate that random puzzle complexity cannot be selected when the size of the puzzle is 30 x 30.
• Fixed a crash that happened when the first puzzle of a game session was started with no advanced assist options enabled and then said advanced assist options were enabled mid-puzzle.

Randomly generated puzzles are here! Now, you'll never run out of puzzles to solve again! Assuming you don't mind solving puzzles that don't form images, that is. To generate a random puzzle to solve, just click the Play button on the title screen (renamed from "Puzzle select"), then select the "Generate a random puzzle" option. You can then pick the size of puzzle you want to generate, as well as the relative complexity* of the randomly generated puzzle**. If you want to stop working on the puzzle and save it for later, just pause and select "Exit". You'll be prompted to save it to your user puzzles, where you'll be able to continue working on it at another time. You can also save the puzzle once it's completed if you liked it, or even share it using the clipboard sharing method.*** Additionally, new puzzle assistance options have been added to the game. You can now enable an assist that will point out rows and columns that can be worked on, to help you narrow down where to look. Also, enabled by default is a new, more advanced method of fading out hints**** that can more accurately determine which hints need to be greyed out. If you feel the new hint fading method is a bit too helpful for your taste, you can always disable it to return to the original method that the game launched with. A full list of the changes made can be found below. I hope you enjoy the new additions!

• Added random puzzle generation.
  • Random puzzles are generated by filling in a puzzle randomly. The total possible combinations in all rows and columns is then added up to determine its relative complexity. If the amount falls within the expected range, then a solver runs to make sure the puzzle is line solvable. If it is, then the player is presented with the puzzle. If not, then a new puzzle is generated, and the process repeats. As a result, the time it takes to randomly generate a puzzle varies based on the size and complexity the player has selected.
• Added an option to use advanced hint fading.
  • Enabled by default.
  • This option uses a puzzle solver to comb through the hints and see which ones should be faded out. It catches completed hints that the original hint fading technique would miss. But it doesn't cheat; a hint can be faded out using the new fading method even if the puzzle is filled in incorrectly.
  • This option cannot be used if hint fading is disabled.
• Added an option to only fade out hints that are Xed off, meaning the number group associated with it has either an X or a puzzle edge on either size of it.
  • Enabled by default.
  • If you disable this, then, with the new hint fading technique, hints will be greyed out even before you have put Xes on either side of them.
  • This option cannot be used if hint fading is disabled or if advanced hint fading is disabled.
• Added an option to automatically X off hints once they're complete.
  • This option cannot be used if hint fading is disabled, if advanced hint fading is disabled, or if the option to only fade hints that are Xed off is enabled.
• Added an option to point out rows and columns that can be worked on.
  • When this option is enabled, a square appears next to the hints of any rows or columns that have something that can be done with them.
• Various minor optimizations, bug fixes, and improvements.

• Added an option to show or hide the currently selected primary click type. (Options > Puzzle > Puzzle Appearance > Show current primary fill type when using mouse)
  • If you uncheck this option, I recommend changing your mouse input settings so that left click is always "Fill", rather than "Primary Click". That way, you don't inadvertently change what the left mouse button does via the mouse wheel without a visible indication that it happened.
• Added an option to show or hide the checkmarks that were recently added next to the titles of completed puzzles in puzzle select screens. (Options > Appearance > Show checkmarks for solved puzzles)
• Reduced text margins to allow more space in menus for the new options.
• Fixed a bug where the puzzle shown on the solved puzzle screen would display at an incorrect size after changing the resolution.

This update adds achievements for completing abstract puzzles! There are six total, one for each puzzle size category and one for completing all of them. If you've already completed some or all of the abstract puzzles, simply opening up the game should cause any resulting achievements to immediately pop up. Additionally, puzzles in the puzzle select screens now display a checkmark next to the title of the puzzle when they're completed, and, in the main menu, a checkmark displays on the puzzle collection button (either "Original Puzzles" or "Abstract Puzzles) when all the puzzles in said collection are complete.

This update adds 100 new puzzles for you to solve! The puzzles are different from the original ones included with the game. For those, much of my focus was on making recognizable pictures, rather than the puzzle itself, so most of the puzzles were relatively easy to solve. For this update, I decided to create abstract, unrecognizable puzzles instead, so I could focus on making puzzles that were more challenging to solve. As a result, this puzzle pack represents a pretty significant difficulty bump from the original 200 puzzles. Though the puzzles may look somewhat random, they were not randomly generated. I hand-designed and test-solved each one. Each size category, from 5 by 5 to 25 by 25, has half the amount of puzzles it did in the original puzzle collection, so there are:

• 4 5x5 puzzles
• 24 10x10 puzzles
• 40 15x15 puzzles
• 20 20x20 puzzles
• 12 25x25 puzzles

• Improved counting so that filling in squares during a count no longer automatically stops the count when you stop filling in squares.
• Fixed a bug where pressing start on the main puzzle select screen would crash the game (embarrassing...).
• Changed puzzle completion achievements to no longer use a puzzle completion count Steam stat and removed the stat. This change means there should no longer be any circumstances where achievements pop up when they shouldn't.

2.00.01 patch

Additions

• Added the ability to turn on or off individual sound effects. (Options > Sound > Sound effect settings)
• Added an option to increase the thickness of the five-line dividers. (Options > Puzzle > Puzzle appearance > Use thicker five lines) Note that this has little to no effect at very low resolutions.
• Added an option to turn off the expanding ripple of color that appears when you solve a puzzle. (Options > Animations > Show puzzle solved ripple effect)
• Added an option to disable the button inflation/deflation animation. (Options > Animations > Show button inflation animation)
• Added an option to not have background music pause upon solving a puzzle. (Options > Sound > Stop music on puzzle solve)

Changes

• Changed the text of some option buttons to start with a verb for more consistency.

Bug fixes

• Fixed a bug where, after creating a puzzle, testing it, then editing it and retesting it, the number hints would become smaller than they needed to be.
• Fixed a bug where holding down a directional input and a page change input on the puzzle select screen could cause two buttons to appear as if they were selected at once (if UI animations were enabled).

Version 1.04.00 is a patch that addresses some quality-of-life issues with the puzzle creation and sharing features introduced in 1.03.00.

Changes

• Added a '+' button to create a new puzzle on the user puzzle select screen.
  • On keyboard and controller, the puzzle creation menu can be accessed using whatever key or button is assigned as the pause input.
• Added a button to test solve puzzles directly from the pause menu of the puzzle editor.
• Changed what the first button of the "puzzle solved" screen says and does based on context:
  • For built-in puzzles, the text and behavior is unchanged. ("Next unsolved puzzle"/"You're all done!")
  • For puzzles that were copied from the clipboard (that others shared, presumably), the button is now used to directly start playing a different puzzle that you've copied to the clipboard.
  • For saved user puzzles, the button is now for sharing the puzzle (copying it to the clipboard).
• Changed it so that when a user puzzle is deleted, the next closest puzzle/page is selected afterward instead of always going back to the first page.
• Changed how the game determines whether or not there are any unsaved changes when editing a puzzle. Previously, it simply set a flag once the puzzle was modified, meaning it would claim to have unsaved changes even if you then modified the puzzle again to bring it back to its original state. Now, it compares the current state of the puzzle to its initial saved state.
• Changed the pause input to be classified as a universal input. This fixes an issue where the pause input could be shared with another interface input, causing a potential conflict. For instance, previously you could set both the pause input and the select input to the same button on a gamepad, and then, when in a puzzle, if you opened a pause menu, you could never select any of the options because the pause menu would be exited before a selection was made due to the order of input processing in the code.
  • Unfortunately, this means that the Escape key on the keyboard can no longer function both as a back input and a pause input. Instead, the pause input on keyboard now defaults to the space bar. However, your currently configured inputs won't be changed unless you reset them to their defaults. If you leave them be, you won't be able to access the puzzle creation menu from the user puzzle select screen via keyboard because the Escape key will cause you to exit the puzzle select screen before the puzzle creation menu has a chance to open. You can always just click the new "+" button, though, or access the puzzle creation menu from the main menu.

1.04.01 patch

• Fixed an issue where the current music track would restart if you clicked the "Play another puzzle" button with the last played puzzle still copied to the clipboard, then copied another puzzle and clicked the button again.
• Fixed an issue with the transition from one clipboard puzzle to another.

About the update

Additions

• Added puzzle creation and sharing:
  • Added a puzzle editor.
  • Added the ability to copy puzzles to clipboard in text format and read in puzzles from clipboard in text format.
  • Added a user puzzle select screen, where saved puzzles go and can be played, edited, shared, or deleted.
  • Added the ability to paste in puzzles from an external image editor when using the puzzle editor. When this is done, dark pixels are interpreted as filled in and light pixels are interpreted as blank.
• Added a new track, an alternate version of the main theme.
• Added a new option to change what track plays on the title screen and in puzzle select. The new option is found under playlist settings. You can also set the track to "None," if you want to hear music during puzzles but not on the title screen or in puzzle select.

Changes

• Changed the two pop-up dialogs that show up before and after applying display changes to have an animated transition between them when UI animations are enabled.
• Changed pop-up dialogs to have consistent movement directions during transition animations depending on the pop-up type: info dialogs (the ones with only an "OK" button) now always travel in from the bottom of the screen, while confirmation dialogs (the ones with two buttons, usually "Confirm" and "Cancel") always travel in from the top of the screen.
• Changed the page change animation in puzzle select screens to always be based on the direction of change implied by the input given, even when wrapping back to the first page or from the first page to the last page.
• Changed there to be only one options menu instance instead of two.
  • As a result, the main menu screen had to be rearranged to accomodate the buttons to clear all progress, reset options to defaults, and view credits. Previously, those buttons were simply part of the options menu when accessed from the main menu, which was possible because of there being two different options menus that were kept in sync.
• Changed the track that plays on the title screen to be (by default) the new alternate main theme.
• Changed certain confirmation dialogs to not respond to back input, requiring one of the two options to be intentionally selected.

Bug fixes

• Fixed a bug where, when using a gamepad or keyboard, the game would crash when trying to select a preset theme's main color using the expanded color picker (yikes!).
• Fixed the "RGB" text above the expanded color picker to re-center each time it changes instead of just centering once.
• Probably fixed one or two other bugs that I can't remember.

1.03.01 hotfix

1.03.02 patch

Additions

• Added four more custom themes that can be configured, for a total of five.
• Added buttons to copy and paste individual colors in the custom theme editor.
• Added a toggleable option to have custom theme colors update in real-time while picking them.
• Added a background fade effect to the puzzle pause menu.
• Added a prompt to the custom theme editor asking whether you want to keep or discard changes when exiting the editor.

Changes

• Optional extra line info text changes:
  • Moved the column info text to below the puzzle. The row info text is still to the right of the puzzle, but is now centered relative to the puzzle.
  • Changed the text to be a bit more informative.
  • Changed the text describing the extra line info option to also be more informative.
• Changed the custom theme editor to support copying all colors over from custom themes, too, and not just the preset themes.
• Removed the R, G, and B labels on the sides of the color picker.
• Changed the color picker square outline to be both black and white so that it's easily visible regardless of what color is selected.
• Changed how puzzle sizing is determined in order to maximize screen real estate.
  • Changed the optional puzzle number and size text to be where the timer normally is when the timer is disabled.
  • Changed the puzzle to resize itself depending on whether or not the timer is there, similar to how it already did that with the puzzle number label.
• Made some minor optimizations.

Bug fixes

• Fixed missing sound effect and controller rumble in tutorials.
• Fixed the solved puzzle transition sound effect starting too early because of a change made in version 1.01.00.
• Fixed a bug where the info dialog that shows up after resetting all settings to their defaults sometimes wasn't visible.
• Fixed a bug where the puzzle number and time text of a button in the puzzle select screen erroneously used a smaller font size when the actual puzzle title needed to use a smaller font size to fit. Only the puzzle title needed to be a smaller size.
• Fixed a bug with the transition from a paused puzzle to the puzzle select screen that became more noticeable once the pause menu background fade effect was added. The bug was that the pause menu instantly disappeared when the transition started instead of staying onscreen. This became a lot more noticeable once the background fade effect instantly disappeared as well.
• Fixed optional auto-assist changes to a puzzle being immediately visible during the transition from the puzzle select screen to the puzzle.
• Fixed a bug where multiple buttons in the playlist and custom theme editors could be hovering, as if all selected, after changing the resolution.
• Fixed a minor bug where the selection could be changed after clicking an input in the controls editor if both the select and move inputs happened on the same frame.
• Fixed a bug involving page change inputs and the color picker.
• Fixed a bug where the game could get stuck in an infinite loop after trying to change a gamepad input in the control editor.

Additions

• Added an option to automatically fill in empty spaces in rows and columns when all empty spaces in the row or column have to be filled in to complete it.
  • This option can be found at Options > Puzzle > Puzzle assist > Automatically fill empty squares when required
  • Since this option does quite a bit of the work for you, most players will probably want to leave it disabled, I imagine.
• Added an option to display the current puzzle number and grid size when working on a puzzle.
  • This option is found at Options > Puzzle > Puzzle appearance > Show puzzle number and size
• Added an X button to exit tutorials from any page.
• Added the current version number to the lower right corner of the title screen.

Changes

• Changed puzzles to not start the "puzzle solved" animation until all fill animations are complete.
• Changed puzzles to resize when needed to make room for the extra line info text and puzzle number/grid size text. Previously, the extra line info text was cut off at certain aspect ratios/resolutions.
• Changed how gamepad and keyboard input works during tutorials. Previously, the "Select" and "Back" buttons acted as alternate inputs to page forward and backward through the tutorial. Now, the "Back" input exits the tutorial and the "Select" input does nothing.
• Moved the option to enable/disable hint fading to the puzzle assist menu to make room for the new option to show the puzzle number and grid size.
  • It's now found at Options > Puzzle > Puzzle assist > Fade completed hints

Bug fixes

• Fixed a bug where the extra line info would temporarily be positioned incorrectly if the game instance started with it disabled and it was enabled during a puzzle.
• Fixed bugs that happened when using the "Always overwrite" option in conjunction with auto-X assist options.
  • Fixed mismatched undo and redo that happened when overwriting automatically placed Xs.
  • Fixed a bug where overwriting an automatic X with a placeholder would immediately overwrite the placeholder with the X again.
• Fixed a bug where the custom theme was being saved (written to file) on exit every time, even when it hadn't been changed.
  • As a result, also fixed a bug where options menus were being reconstructed unnecessarily (to account for custom theme changes that hadn't actually occurred).
• Fixed the color picker in the theme editor not resizing after a resolution change.
• Fixed fade animations in tutorials fading to the wrong color when in a highlighted row or column.
