Interesting concept, and love the art style. Very nice!
I had to play using a Gamepad, mainly because the key press didn't feel responsive enough for platforming.
The vertical corner collisions could also be a tad more forgiving. I had at times felt like I landed square, only to have her slide of the corner and fall. Not sure if that is by design based on her state, but it was a little frustrating. I hope that's helpful!
Either way, some solid platforming sections.
Great work! Would love to see more. : )
