Great audio, art and tutorial. As others have mentioned, it took quite some getting used to the controls (or rather, control). Even after some significant time, I didn’t feel like I could consistently do what I wanted (especially, shooting ice/fire). Using just SPACE is a fun take on the theme, and I am confident with more practice I could get it, however I think that barrier gets in the way of what is otherwise a fun little runner.
But, what’s a game jam for if not trying whacky things? Great submission!
