Analysis: The real quality of this game is owed to its superb visuals and sound. The visuals are clean and crisp, reminiscent of Tonypa's pastel-on-white works, and a bit of scrolling background (a la Drifts) lends itself to calm the frenetic pace of the game.
And frenetic it is, largely due to the intertwining of the game's jazzy, disco track and the behavior of the asterisk sprites on the screen. This is not a game for the hearing (or rhythm) impaired. In each stage—delineated by a shift in the color scheme of the sprites falling from the sky—your attackers will adopt a new strategy in colliding with you, but will do so in time to the beat. While at first notion, this would seem to make the game easier to handle, it in fact just adds to the tension and absorption of the game.
I suggest headphones.
The instructions for the game are brilliantly simple and to the point, exactly the kind of intro I like to see (and again, reminiscent of Tonypa's games such as Touchme). You must avoid touching anything, and you start the game with a limited, non-recharging bar of repellent: press the mouse button down to push away all of the sprites near you. The bar drains fast, though; expect no more than two or three seconds of usage per game.
My embarrassing admission: I haven't gotten past the second 'phase'. Here's a hint—just because the color changed, doesn't mean the music has changed completely.
