It's working for me, although I can't hear any sound or music. This seems like a potentially fun game, but it's difficult to tell where exactly the player square is in relation to the obstacles as they come up, so lots of unintentional collisions. (Especially when you move the square all the way to the top of the screen and it basically leaves the viewport.) Also, I managed to figure out the controls on my own, but would have appreciated some instructions.
