I had a lot of fun playing this one, though I struggle hitting the enemies, not sure if was the collision, my mouse or just me XD but I really enjoyed this one, especially the boss fight, the soundtrack used it for it was nice, it makes me feel the combat was frenzy.
There is room to improve the fight and the level design, I think it can have more elements to interact in the world or maybe less walking (a smaller level?) and the bloom used at least on the boss fight, it blinded me when I tried to cure my self (not sure if that was intentional).
About the game concept, I liked the idea of graveyard digging and the way you regain hp was creative. Well done :) !!
