Movement felt pretty good. Enjoyable moving around the map.
I really liked how things got lighter and darker, depending on what section you are in. That looked good. Background art was nice. Big boss drawing was good. (The black thing with the knife scared me because I didn't see it at first)
The idle animation is too jarring though, and the attack was pretty short. I couldn't get past the large mushroom boss to save my life. He was impossible to hit with the little attack distance and touching him would 1-hit me to death. Sooo not sure what happens after that unfortunately. Unless there's a trick to that?
