Description:
The point of ‘Blocked Off’ is to block off areas without any balls. To create a new wall, shoot a laser so both sides touch an existing wall before touching a ball. If no balls are in the area on either side of the newly created wall, it becomes blocked off. When 70% of the screen is blocked off, the level is complete.
Another ball is added for every level completed.
Controls:

Power-up items:

Lightning bolt: fires the laser 2.5 times the normal speed
