I think it might be bugged? Some moving blocks didn't color their starting tile all the time. If you fix this or I'm doing something wrong, please let me know so I can play the game again, even after the jam! I like this kind of puzzle game.

Thank you for bringing this to my attention! It is a bug which i experienced rarely when minimizing the tab, so i figured it wouldnt be that bad. If i were to guess why this happens it would be either because the game is set to run in background or because of some improper deltaTime implementation. Unfortunately i am unable to fix this until the end of the voting period but ill make it my top todo priority.
