Firstly criticism - camera should probably move a bit, or make it so I don't need die and remember where to go on my first jump.
Good things - it looks nice, and it is pretty oke, idea is cool too
What it lacks a lot - the feel of it, I don't really have much acceleration and so it feels slow, even tho I move at 100 something (I just may like to feel like going fast, who knows)
Still for a 3 hour game, it is nice, good job :3
