Really awesome sprite work, fun contrast in the color of the sunset sky and the dark environment with easy-to-see green spots/characters of importance. Nice mechanics, fun little arcade style game! I guess my only gripe is that you tend to go through each power a little too quickly to enjoy them and since some require directional input, I didn't think some of them worked my first couple go-arounds until I actually did look in the corner (I read the instructions, that's kinda on me)
Both in their size/shape and some sounds, got some big Kirby vibes, nothing wrong with that at all.
