This update fixes several bugs and balance issues introduced in v1.10 as well as fixing the lag when encountering lots of monsters/obstacles (pretty noticeable sometimes on Steam Deck).
One big UI issue was the lack of potion tooltips when playing on controller or Steam Deck. All menus with potions now show the full potion tooltip. So with these two improvements to Steam Deck playability, I can say without reservation it's a damn great experience on that platform. One other neat feature: you can mark Hawker items to buy later. Gameplay changes:

• New monster: Skeleton Archers
• Added the ability to mark Hawker items to buy later. These are highlighted on the Hawker menu and the Hotel Map.
• Removed intelligence bonuses from TOUCH and EXECUTE and lowered the thresholds slightly on the latter to: 20/40/60/80
• Lowered VORTEX damage, since it was arguably the most efficient spell in the game
• Added spike rooms into map generation
• The chance of finding swords and revolvers has been increased, since these particular items are so important but armor items are mostly interchangeable.
• Now preventing levitation with Big, but allowing it Statue Form.
• Slightly lowered the speed of the Spiridus
• Reduced the spawn rate of Iron Maidens

• Fixed the performance issues related to too many monsters by caching monster sprites. This can be disabled in Options if it causes any problems, but it should resolve performance problems on Steam Deck.
• Fixed a bug where hovering a particular icon showed the real identity of a potion. Yikes!
• Fixed an issue with Options on Steam Deck where using the cursor didn't actually change options
• Now preventing transmutation to the same potion
• Now grouping Primer menu by bundles
• Fixed an erroneous log message when using BLAST and hitting no targets
• Added some achievements related to SECRETS
• Fixed an issue where template rooms that should have items sometimes did not
• Fixed a display issue when Officer leveled up and full healed
• Fixed a bug related to fighting Fane but leaving to go somewhere else
• Apparently seeds were completely broken (such that map generation would diverge immediately after the first room) since the last update. This should be fixed
• The streak counter on Despair mode now runs negative. Sorry.
• Fixed an issue with allies not fighting mimics
• Fixed a bug where you wouldn't stop resting when being attacked by mimics
• Fixed a minor issue where the player is less than 1 hp from full and full hp is displayed, but books are not read yet.
• Fixed a map generation connector issue (you might have seen areas blocked off strangely)
• Fixed some issues with monsters pursuing you due to visibility or noise
• Added option to Morgue to toggle sorting between Score and Date and defaulting to the latter so that your newest entries are at the top
• Fixed a bug with chairs spawning in walls
• Added icon to Floor 10 in Hotel Map showing the GOLDEN KRONE
• Unexplored floors are now highlighted differently than explored ones on the Hotel Map
• Changing status description for multiple stacks to say "Status+2" instead of "Status-2", which was confusing.
• Fixed "NaN" hit chance descriptions when deluded
• Removed Vortex Solomonari from the Rafters
• Adding current version to Options and Morgue files
• Fixed a "double level up" issue which actually turned out to be a missed stat increase from an earlier level up
• The Ring Acquired menu now closes on the press of any button
• Fixed a bug with diagonal buttons on the Hotel Map closing the menu
• Fixed a save/load bug where the levers in the Dungeon no longer appeared
• Added that sweet Zyalin art from the v1.7 update screen as a collectible page in the Books & Letters menu
• Showing the same green flashing on your character when Heavy Poisoned as just Poisoned
• Fixed a bug where Antidote wouldn't remove Heavy Poison if you had no Poison
• Styling changes to potion tooltips
