I absolutely adore the vibe and personality of this game. I really enjoyed all of the bosses, and the payoff with Tony at the end was great. The art style is fantastic.
Just mirroring what some other folks have said; a lot of the bosses could just be beaten by tanking the damage and slashing repeatedly without much need to dodge/move around a lot.
I also think I accidentally missed out on any new limbs? I thought they were boss rewards but never quite figured out where to equip them from (either before or after a fight)
Even with that being said, this game is one of my favorites so far.
