Really interesting idea. Although my eyes probably do bleed as I write this review, I enjoyed the game. The music matches it very well, movement speed is just fine, the background moves fluently. And there's even a fullscreen mode and a scoreboard.
What might be an interesting thing to try (or as a 'hard' game mode) to make the white balls speed up and slow down accordingly to the music's pace. Also, do your secret medals work? If there's some additional trick you have to do, then they're ok, but if it's just about getting 5000 (10k, 20k) points, they might be broken.
And, is it just me, or do I suddenly want to support jupitron as our supreme commander and world leader?
