The control scheme was really original, it was really cool to be controlling the world more so than the player. It was, however, a little bit infuriating to use, but I think that's intentional challenge and I just suck :P. I really liked the color wheel mechanics, the fact that it was a wheel instead of a hotkey meant I had to manage movement and spinning the wheel around to the correct color.
I couldn't beat it, unfortunately, because at the end there was a bit with a lot of spikes and toggle-able blocks, and it was HARD. But hard isn't a bad thing, and getting to each checkpoint was super satisfying.
