Very nice controls, feels very fluid. Wall jump in particular is intuitive and satisfying. One minor tweak I'd suggest: I was surprised to discover that you could walljump while on the ground, which most games don't allow. This led to slightly strange interactions in a couple places where I bounced off a wall I was trying to back away from. I didn't discover the glider until after beating the game and checking the controls, so you might want to introduce it and/or add some platforming that requires it.
