I like the pixel art of the character a lot and appreciate the respawns! It took me a LONG while to beat it because I was struggling with controls and really tight inputs. Have you at all considered making D +C into just one jump button? It could be one you can hold down for a moment still.
Charming game, even if I almost crashed out over difficulty. Interested to see where you will go next! The mechanics were cool, albeit hard to use.
