I’ll admit I’m completely baffled. Got to the third section, where we start collecting stars. It seemed that you have to walk thru white blobs when the music progress upward and black blobs when downward, but that didn’t hold true, and I gave up in frustration after a dozen or so attempts.
It’s a great idea overall, the idea that figuring out how to play the game is The Game. But I think you erred a bit on the side of obscurity.
