Very good and challenging platformer! It’s cool that you managed to make so many levels in such a short time.
It took me a while to get used to controls and to the momentum mechanics, and even now that I have finished the game I don’t completely understand it. I mostly just smashed keys randomly until it started to work. :-D
Seeing that you are going for a retro feel, I could suggest to add some cool post-processing effects like bloom and CRT effect. It will look awesome with your game!
