Really interesting! I like your interpretation of the theme and I find the movement system to be unique. I feel that having your attack also act as a movement option could open up for some interesting gameplay. There's something satisfying about swooping through an enemy and quickly dashing to evade a hazard.
One thing I think that could be better would be adjusting the camera zoom to be a bit larger; there were several places where I accidentally went directly into spikes that I didn't know were there.
Nice work!
