very challenging, I love your take on the theme of taking damage to clear the levels. Its a good level of difficulty with a variety of ways shown off of how the mechanic can be used, the movement has a pretty smooth feel to it after getting used to it
The dash jump dash bit is the one part I thought was a little too precise, and became a bit annoying after a while. I must of been stuck on it for 10-15 minutes :')
I think the glass section at the end is my favourite - I thought at first it was going to be an annoying random multichoice section but the way you have to navigate to the parts with the right number of hearts is very clever puzzle
