While I like the idea of a creative and experimental menu, I couldn't figure out how to start the game, so I'm not able to rate it :(

Aw, sorry to hear that! If you're interested in trying again: The angle is a bit funny at the start, but as long as you hold LMB on one side and drag it fast enough to the other, you should be able to get the marble moving fast enough to break the tape (there's a certain speed you have to hit to get the better camera angle). Getting it in the hole next to the play button sign will start the first level.
Disclaimer: I didn't consider trackpads when I made the controls, so if you're relying on one, I don't blame you at all!
