A musical colour-mixing puzzle game, where you add and subtract colours.

It includes procedurally-generated zen music, based on the number of colours you've collected.

I really liked that! Great work as always, Xavier. 

Very peaceful and calming experience, and the puzzles are quite interesting. It takes a bit to figure out exactly how to play, but once you do it's very fun.
