This reminded me of that one japanese game show where the contestants had to fit in an incoming wall with a cutout that would get increasingly absurd. Besides all the input bugs (which are understandable for a game jam) I liked this game. I especially like the coin mechanic which makes the player try some risky strategies that might end up costing them a piece. I would suggest that the wall patterns changes when you are down to 3 cubes to be more restrictive since it didn't seem like I would get any 3 block sized patterns.
