Very fun game! Liked how you got different new powers everytime you got a color back :D Only thing I noticed was that the jumping was very flowy or I felt like maybe there could have been more of a gravity pulling me down, this is obviously just my opinion :) Other than that I really liked the game, keep up the good work!
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
