pretty fun idea! i like the concept of "dribbling" your character to jump higher :)
i think the game speed was tuned a bit too slow, i feel if everything happened about twice as fast, the game would be a lot more engaging. the physics are very floaty... still, once you get into the flow of things, the levels do flow quite nicely, quite good for your first entry id say, would love to see this polished up and expanded upon :3
