I really like what you were going for and I think that the idea is pretty well executed here. I think that you could've done with making the jumps feel a bit lees floaty and have it so that you don't slide so much once you let go of the run button. It makes it feel like you're on ice all the time. I would also say that having lives is a little frustrating since I just have to redo everything if I fail too many times. But I like the sounds and overall great job on this!
