Nice puzzle game! I really liked the sound that the pieces make when dragged. It gives a nice tactile feel that is addicting! I also found the little guys to be rewarding. Two things that would make me play more would be:
1. To be able to get past the dropped pieces. If you block your entry it's game over, so you have to start at the other corner to have an advantage. Also there are spaces where a piece fits but can't go there!
2. I would have liked a grid background so that I can see more easily where a piece fits.
Great game for the jam! Loved the tiny robots! Have a nice day!
