Nice job on the game! I would recommend turning itch.io's fullscreen setting off for the game. If I click very precisely I can click the correct one (Unity's), but most players might miss it becaus it's extremely hard to click it. The itch.io fullscreen button will keep the game in a box and Unity's fullscreen button should work fine, so itch.io's button should be left off for this game. You can make this change without changing the game file. Other than that, good work on this!
