Definitely an underrated game. Didn't expect there's a boss fight at the end (it takes me some time to beat it as the player only has 1HP. I recommend giving the player a health bar during the boss fight or it is frustrating). The only complaint is related to a mechanic not intuitive at all, and I believe there will be lots of players give up at that level, which is the player will automatically perform a super jump when you return to the human state.
Btw, feel free to play my game, you will be interested :)
