I did play this game. And it rules. The music is inspired. The stress and feeling of personal wobbliness is perfect, the kind that makes you swerve your body around imagining that will somehow help--as your marble falls to its death. Good for racing opponents in 2 player mode, because you will both be thrashing around on the floor. One of the best games that doesn't try to rely on intense speed or outstanding detail in 16 bit graphics.
