Really great! I love how as you get farther along, the cubs start doing cool things in line with the music. The whole game has a really impressive level of polish. At first, I didn't really like that it was hard to know where your ball was in 3D space because of the static camera angle, but eventually I came to accept staying near the middle as part of the challenge. My only real gripe is that like many other submissions, the game does not provide a button or option to exit from the game menu, forcing players to use OS keyboard shortcuts.
