It's a nice approach but here are my takes:
Your controls are to stiff, pls use some sort building momentum
The music is repetative , change the the track every once in a while, the track you made is good, but you can do better (not in a frame of a gamejam, but do more of it! really liked the music the first time playing!)
Randomness in platformer-style game is really hard, so kudos that you tried! But if you incourage randomness, you have to tweek other parameters, such as speed ;)
Please make more games!
