Big bubbles split. Small bubbles get through. Keep moving, line up your shots, and hold the backline in this pixel-art arcade shooter.

Fight through eight arenas, from The Courtyard to Meltdown. Slippery floors, hot lanes, armored bubbles and the Overpressure Core keep the rules changing as you climb.

Earn at least two stars to unlock the next stage. Replay for better scores, faster times and clean clears.
