I've enjoyed playing this! Difficulty spikes right from the start, but becomes enjoyable as you get used to controls.
Music is awesome and really gives you adventure vibes.
Some of the mechanics felt too stiff which gave me feeling for the game to be unnecessarily difficult at some moments. Unless you aimed for making it more of a rage game, haha =)
Particularly, I would nerf falling acceleration. It just feels like you reach the speed of light in 1 second lol
Also making a platform slow down before changing direction would help to better see its movement area.
Those are minor cons, but they gave me most of my hard time in game, haha =)
Anyways, nice entry. Good job!
