This could be decent fun, and I understand that you probably made this in around 3 hours like the rest of us. But I think the controls are too floaty, and bouncing after landing on a platform makes it difficult to time jumps.
Some of the palettes also don't work. One of them was to light, which made it difficult to distinguish the player. But the one I have a really big problem with is the one that flashes between different colors rapidly. That's not a cool effect, that hurts eyes and could cause a seizure.
Fix that up and I think you'd have a pretty good game here.
