It took me a while to realise that I could roll with the arrow keys as that wasn't mentioned in the tutorial. After I figured that out though it was very fun trying to control the character. It felt quite difficult to control and chaotic but in a way that made it funny, not frustrating so good job with that!
I think the breathing in sound effect was quite confusing because it was much shorter than the time it takes to fully charge the breathing mechanism. This meant that I kept releasing the button before I should have.
Overall though, really good interpretation of the theme, excellent art and music and fun to play.
