Your goal is to grow balls that fill up 2/3 of the level. That would have been easy if not for the renegade bouncing balls interrupting the process.
Try to set a highscore!
Fill up 2/3 of the screen. Hold the mouse down to create a filler ball. Release the mouse to freeze it.
You have a limited number of lives and balls each level. If you squash a bouncing ball, it will reappear at the top right corner.
