Changed level selector icon, should be clearer what it is.
Level unlock popup (+1, +2 puzzles) will make the level selector button blink more, so players will notice it more.
Default hotkey for hints is now F (H also works) instead of TAB, so the game will not give a hint when ALT+TAB'bing on Steam. Hint popup will appear once with the new keybind for existing players to inform you of the change.
Level selector tutorial popup will appear even if you don't use hints. New players will see it at level 4 and existing players will see it once on the start of a level, if they never seen the popup yet.
Reminder popups for using hints and for level skips are shorter, will appear after a longer time and will stop appearing after seeing them 3 times each.
Lowered hint cooldown.
Made one of the starting level easier. I will add more easy levels in the first content update.
