An interesting idea. The controls felt a little weird, but I did end up getting the hang of it. The colour mechanic was interesting and was a nice interpretation of the theme. However, I don't think it was explained well enough and the colours were a bit too similar for liking; At times it was hard tell which colour I needed to use to progress.
The music was nice enough, no real complaints there.
As for Geometricness, everything was a square or a rectangle so 5/5 there.
I will end by saying I got soft locked by getting stuck in a wall. Bugs happen, but still quiet annoying.
Overall, not a bad game considering the time constraints.
