This one needs way more attention, very cool idea. The wall jumping mechanic is solid, dash is good, music matches the atmosphere and the graphics are good.
For feedback, my only nitpick would be to make movement slightly less floaty. To brainstorm: a short lerp for acceleration, probably a 0.15-0.2 second lerp in from 0 to max acceleration and max to 0 when key up would keep it feeling responsive and reduce the floatyness.
