Nice platformer, I see you put a lot of effort into level design.
I would suggest starting easy. Maybe I am just bad, but I barely figured out how to use the parachute and wind tunnel correctly. Perhaps give the player some space to familiarize themselves with the game mechanics.
Also, you have art style mismatches. You have so many things going on, It's hard to take in all at once, maybe polishing a smaller feature set might have worked better, though I am no game design export.
Overall great game, nice concept, great mechanics!
