This is a great puzzle game which makes great use of the theme. I love the use of color for the puzzles. This is one of the best games of the jam but I do have some feedback:
The music is very quiet. I didn't realize there was music till I looked at someone else's comment.
pushing the blocks around when you move into them makes jumping on them and navigating around them really difficult but also doesn't add anything to puzzles. It sucks to set up your puzzle solution and accidently bump a block into another and mess up your colors so that you have to restart.
There seems to be a bug where changing the color of a block also changes nearby blocks of the same color. I had a red block on a purple switch. I split up a blue block and put it on the purple switch with the red block to press it. However, when I did that, the other blue block became purple for an unknown reason.
Does the game lack a way to quit/close the application? Pressing escape would just cause my mouse to appear on screen.
Other than this, I loved the game. It was really fun.
