ZoneBall is an arcade game. Try to control at least 80% of the playfield while dodging enemies to win a level.
Here's the ZoneBall storyline:
You are in a laboratory and your job is to isolate nano-robots which were released during an accident. The only way to clear the area is by shooting a laser beam over the surface of your probe to modify its molecular structure and build walls. The level is considered to be cleared as soon as 80% of the playfield are covered with walls.
