Cool game idea! I like the idea of combining colours on the fly. I think the controls are a little awkward - perhaps number keys 1, 2, and 3 would have been easier to press without letting go of WASD. I also think the ability to wrap around to the other side of the level makes it too easy as you can just lead the enemies in one direction then appear on the other side and lead them back again. Even so, this was fun to play and the screen shake is a very nice touch! Good job on the submission.

Thanks for the feedback! I realised during playtesting that wrapping around the screen was overpowered but decided to keep it because it was more fun that getting stuck. A better difficulty curve would fix that I believe.
The buttons are mapped to R,G and B to make fore more hectic gameplay but I understand it being clunky.
