Not bad, controls were pretty solid, way better than some I have encountered. A few suggestions for the future: the screen size vs the game play space aren't quite the same, which led to me dying a few times because I had to navigate part of the level that was off camera, and some of the color zones didn't register to the correct color (on the 3rd level I could stand in some green and blue zones as the red ball). Also, you can air jump indefinitely, which mitigates some of the intended challenge of the platforming, so having a grounded condition to let you limit jumping will help keep your players playing the level as intended. I thought the music was really nice, a simple and short loop, but pleasant and didn't become grating as some short loops tend to.
