Great platformer. There is 2 things that could help you make it feel much better.
the first and most obvious is the lack of wall stick time, it makes jumping from a wall to the opposite direction too hard for the wrong reasons.
The second is the fall speed, i don't know if it is because you accelerate too fast or because there is no maximum fall speed but it felt stronger than it should.
Air control felt really good (until you start falling), i noticed some lovely coyote time and jump input buffering.
The art was very nice and the music fit really well. Good job !
