Love the color changing mechanic, maybe you could add more colors or even being able to unlock certain colors along the way! I did get stuck on one level, with a black platform on one side of the wall, I'm assuming it's supposed to be moving to allow us to jump over.
Yeah the moving platforms are a little jank, they'll work 95% of the time. I've left levels running for 10 minutes and nothing breaks, then I've loaded the same level and in a few seconds the platform stops, I don't know why but as I said they work most of the time. If a level does break just press R to restart the current level and it should work again.
