Nice design and artwork. Controls are a little challenging, there isn't enough room around the player when moving, I bumped into the coloured walls to often and had to restart which was frustating. I figured out that you can charge your colour by moving to the corresponding coloured enemy but a short tutorial could have worked well to explain this. I liked the 2 frame walk cycle (South park style).
Visually this was a lovely experience but the controls and lack of space made me feel frustrated. Zoom out the camera and add some basic tutorial elements and you've got yourself a really good game. Nice work for 72 hours. :)
