I'm sorry I couldn't figure out the controls. At first I thought I could just shoot things, but that didn't work, so then I thought I had to color match (yellow for yellow enemies, red for red etc), but that didn't work either. There was too much happening on the screen to also read the text while dodging/moving/shooting/rotating colors. The movement itself with WASD was smooth, and I liked being able to switch with 1234, that made sense. I just couldn't understand why or when to switch.
