I think this game loop ahs a lot of potential, it blends some of my favorite genres and it scratched all of the deck-builder itches I would want to see in a game like this, so great job! A few small enhancements I would have liked is a deck/discard counter, and the ability to pause the game. I got stuck a few times in the side or bottom of platforms, and I also found that I could just stand in a safe spot and cycle out all of my curse cards, which made them feel unimportant and like I couldn't actually lose (alternatively, I could just not use spells in most levels and be perfectly okay). I hope this game keeps being worked on, but either way, nice job all!
