Really interesting idea with the way you combine colours together for different powers. 

There was a bit of a ?!?! moment when I started moving with WASD but then was trying to swap and combine colours all with one hand :D 

Only got to the crash unfortunately 

I really liked the idea! Maybe it doesn't fit 100% to the theme, but if you go with angle of "Only Colour at a time" it does. 

Anyways, I thought the game was fun and I would play it again if you expand on it, polish a bit and add more levels!

I don't think it fits the theme particularly well, but I really liked the concept very much. 

Anyways, great work!

For me the same as @mickplouffe.
