Since the majority of people access submissions from this page instead of the store page, I'm going to post the controls in this comment. I had posted them on the store page instead of in-game just to keep the game decluttered. Here goes:
WASD or Arrow Keys: Movement
Spacebar: Hop
Shift: Roll
R: Reset position (useful if you end up flipped on your head, or stuck)
Esc: Exit application
