Beat the game, if I said I didn't like it then I'd be lying! I love the designs of all of the characters. It wasn't as rewarding to complete though, even though it was slightly tedious. If I could give criticism I'd suggest halving the bosses health, as well as adding some delay so you aren't mashing Z to drain it. I'd also suggest improving the bosses jump attack so players don't hide on a ledge and spam heal, as well as some form of indicator, such as a charge animation, before the boss uses a melee attack to balance the Z mashing nerf, if possible.
