v 1.4.1 is out that should work slightly better on OS X Lion
Cool fast paced arcade game. You control your blue bubble with the arrow keys and score points by hitting the green bubbles. A bonus meter will start after each bubble you collect. If you pick another bubble before the bonus time is out (2.5s), you will gain bonus points. The more bonus bubbles you collect in a row the higher the bonus. 12,14,16,18,19,20.
