Thanks to the great feedback of some of you, both in the forums and in the reviews, we've revisited some GUI features and have attempted to improve it. -The classical puzzles now have a next button that will appear as long as you have unsolved puzzles that meet your current filters -In the classical grid view, an icon was added to filter out the puzzles you've already completed. -The helper icon is now bigger, repositioned and more consistant. We're still working on it, so it may get improved further soon! -The options are bigger and cleaner. They ALSO may get improved further soon. -A very weird issue was found when the resolution is at its minimum (1024*768). If you play at this size and had black screen or the like, let us know! We'll fix it, but tracking it will be easier with more paths.
