Very interesting concept. It was confusing at first... but the abundance of hearts laying around made me comfortable with jumping and dashing. I felt like you did a good job introducing each mechanic as the game went on. And I think you also did a great job with puzzle design... I quickly learned that there was a way to maximize movement currency by chaining movements together or like landing on top of a skeleton to bounce.
The artwork and intro are also very well done. Congrats!
