Use the left and right arrow keys to move the ship. It doesn't really look like a ship, so I used a red circle with a triangle in it. Popping bubbles scores points. Every 100 points you get earns you an extra 10 seconds of time. The game is over when you run out of time. The bigger the bubble, the more points you get.
