Duuuude cute pixel art with heavy metal, that was a lot of fun, the gameplay of the game is great, also the visuals are really good, aaand the music/SFX for sure.
The only comment I may have is that there are no white enemies (there seems to be a bug making it named "undefined"), so I never picked any colors and was able to damage all the enemies, this is nit picking though, the game is great.
Very good work in a short time, be sure to check my game as well ;)
