Nice game! It's again one of those game I am screaming more when it suddenly ends! Love the art style, the combat, the consistency of everything combined make the game feel so nice. Love it! I am having the Binding of Isaac vibe here, and that's one of my favorite game of all time!
The upgrade system that uses three elements that seems like each have a special focus is such a nice touch of the game, it just a pity that the game ends before I am upgrading to what I want the character to be. I haven't even tried some of the upgrades yet. My only complaint is that you should expanded the screen a bit, such that the UI is on the side rather than overlapping the level. It does blocks the action a bit and let to some unexpected damage.
But overall, this is a very solid game. Well done!
