This was a really solid combat system. The solid thunk when hitting enemies was very satisfying, and the coin explosion on death felt great. Movement was really smooth and it was pretty easy to navigate through the areas. I liked the atmosphere, although I'd kind of like to know why I'm going to slay the devil. :D Also the character and enemy designs were great - a particular highlight for me was when I heard the first wolf man cry out, I laughed out loud.
Some feedback:
1. I never really felt that Dead Cells-esque ballet of "dodge and attack", I felt like every time I tried to dodge through an enemy I just ended up taking damage anyway. The hit boxes on some of the monsters or their attacks felt a bit overly punishing as well (the demon general's giant sword hitting you while standing behind him or the shield guys stood out to me as very unforgiving).
2. I know other people have said it, but lack of a map. The game was very large and while the trek from campfire to campfire was fairly quick, I reached a point where I didn't really know where I should go next and had nothing to reference. I feel like I knew where I was supposed to go (it was after the double jump), but just couldn't get there. It also didn't help that I seem to have encountered a bug where the camera wouldn't scroll as far left as there was stage, so I couldn't see where I was going (it's in Hell directly across from the first entrance, there's a wolf man there).
3. I agree with what people said about gravity on the jump. I really liked the ridiculousness of the upward force, it felt appropriately over the top for the character as presented, but I'd like to feel some weight behind his descent.
Anyway, as I said I really enjoyed the combat in this game, and as I'm writing this I just remembered you had a stat and shop system too! Very impressive implementation for a game jam (although auto--equipping the blessings would have been nice, I never figured out how to equip them). I'd enjoy more of combat like this, just a ridiculously weighty, screen-shakey smash fest. :D Great entry!
