I really like the concept and idea. I missed jumping in first hole too and I also struggled with controls. I couldn't figure out how to move the blue square (assume I need to), got stuck on walls, and at one point the controls were backwards which I wasn't sure if it was bugging out or if that's what was supposed to happen. I got the blue key but didn't know what to do with it?
Regardless I can see its potential and where it could go with more time that the game jam allowed! Well done :D
