I love the art style for this game, especially the ground tileset. I also really enjoyed having to plan out what color I'm going to need before engaging a group of enemies and how I'll have to switch while taking fire.
However, the movement was a little floaty for me and made dodging and such a bit difficult. In the same vein, wall-climbing was a bit slow and didn't feel like a feature I was suppose to use as much as an exploit. Aside from the player movement, I really enjoyed this game. Great work!
