How many bubbles can you pop? Fly your mouse-controlled ship deep into bubble territory and shoot as many of them as you can in this very challenging scrolling shooter. Avoid touching the walls! Hover over colored powerup squares to change your bullets. Can you get all twelve achievements? Tip: Play the endless "Onslaught" mode first to get a feel for the controls. Holding down the spacebar (or X) will stop your ship from rotating.
