Laser Beams are straight, thin cylindrical energy beams that can be obstructed by Cubes or The Character. Laser beams are often used as a mechanism to detect changes to the environment in Puzzles and often open doors.
Inside Cube Detectors there is a small laser beam with the width of a single cube.
The blue and green lasers work very similarly. Both need a cube to be "blocking" the laser beam in order to function.
The green and blue lasers work very similarly. Both need a cube to be placed in the path of the laser beam in order to function.
The red lasers work differently from blue and green. Red lasers need to be "blocked" from both sides in order to bypass them without triggering them. Red lasers do not trigger from placing a cube in it's path.
