I can't really tell any feedback about the game, because it's quite simple and you probably know all pros and cons yourself But you can't convince me it's not an AI art in the menu (don't worry, it didn't affect the rating I gave to your game)
Your art has different pixel sizes, jpeg-like artifacts and a color pallete that is very similar to a classic AI art. I don't believe it's not AI, but if you make your own art, consider these things, or people will think it's AI.
