I really liked the intro animation and the character’s visual design, they both make a strong first impression. The concept of switching between two states is nice, but it could have been pushed further with more gameplay mechanics other than platform built around it.
The jump sometimes feels a bit unresponsive, maybe adding a small coyote time would help. The audio loop is also a bit short, which can make the experience slightly frustrating over time.
Still, nice work overall!
