Hey! Great job, i really like the concept for this and I think there is a lot you can do with the idea. A complaint I have though is that the jump is so fast that it is really difficult to switch colors in mid air. I got stuck on level 4 at the bottom level. I knew what i was supposed to do but the time frame to swap at the bottom was to difficult and the safe area in the middle was too small. Also, I think the control lay out could be a little different though that's not a big deal. Also maybe a color wheel at the top of the screen to show what order the colors are in because I kept forgetting but also that might just be part of the game.
I really like what you have and I hope you continue with this!
