Why do people submit Halloween games when it's not Halloween? And Christmas games when it's not Christmas? It's Easter time, or will be soon. THAT'S what you should be working on.
Soundtrack is annoying, things are to hard to dodge, or to take, because we can't see them well, or that the car has no space to land. And all you have to do, is pretty much go foward and jump randomly, and hope you don't hit anything, and you pass the level.
Simply no fun to play.
Change soundtrack, make objects more easy to see, slow the car, make it jump lower, and make the levels longuer
