Description:
BlockedOff is based off a game called Barracks (aka Jezzball). The point of ‘Blocked Off’ is to block off areas without any balls. To create an area, both sides of a laser must touch a wall before touching a ball, and if no balls are in that area, 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:
tilt the device to move the laser
touch the left half to rotate the laser 90 degrees
touch the right half to fire the laser

Power-up items:
Super heart:  refills all health hearts
Star:  health hearts are not lost if the laser touches a ball
Lightning bolt: fires the laser 2.5 times the normal speed
