Fun game! I do like the color combining (although that took embarrassingly long to find out I will have to admit). I think in terms of level design, you could add some puzzle elements to it, since I found myself mostly being somewhere and going through the colours to see which one is the one to move forward. Potentially you could add some kinda hints as to what colour is coming up to be able to build a sequence where someone needs to remember or switch between them in a certain order? Anyway, fun game and would be fun to see some more elements added, well done! :)
