I liked it, except for the controls. If possible you should have the character rotate by following the mouse.
Took me awhile to make that jump also but i eventually got it!
I like the movement mechanics, the momentum feels really smooth and fluid. I was hoping to get something like that in our game but we ran out of time. Nice job!
