I think this is definitely one of the best looking games in this jam, and love the idea and level design. The invisible platforms are brilliant! The only way this could be better is with different controls, which you do have with controllers etc. Unfortunately I am playing on my laptop and only have a keyboard so a popup appears when I try to play because I have to use control and shift - not the best choice of buttons. I've not got far enough to say much else.
If you do continue working on this I would suggest making the jumps more responsive. You could make this so you start only with the ability to jump and then as you progress get different abilities like to turn around, double jump, dash etc.
