One of my favorites in the jam. Such a cool main mechanic, and the other mechanics are also working together in a well thought manner. Really fun to play.
That being said I have a few issues :
When you jump, you can't switch directions mid air and it feels stiff.
The jump itself is always the same height, which can easily be changed and add a lot of depth.
BUT, I say this only because you showed a lot of care and talent into this game, and I had a lot of fun with it - I just think you can tweek some things easily and it would feel much better to play.
Really well done!~
