Great game, the art style really stands out and the puzzles are quite interesting. My one piece of feedback is that I didn't quite get how the color coding worked until the last level, that might just be on me but maybe some visual feedback when you move over the color barrel (e.g. spikes grey out a bit or something) or a more straightforward level when you introduce that mechanic where the player is forced to learn exactly how it works would be good.
Would definitely play more if you wanted to put out some more levels after the jam!
