I super love the idea of combining colors and discovering the path in the level, I could even see that being really cool for a game with secret paths or hidden rooms. The only thing I'd suggest is some kind of environmental way of showing that. I know in the beginning we get those over icons that tell us what to do, but later having like red flowers or something naturally in the environment that I would feel smart identifying and knowing what color to switch to because as it stands now I was kinda just spamming every color until something showed up. Still very cool idea! I had fun
