Floor 4B

Floor 4B is an area in B3313.

Description
"A somewhat confusing labyrinth of hallways and corridors. Inoperable paintings dot the walls.

Every so often, the lights go out and reality itself breaks..."

Floor 4B is possibly one of the largest areas in the hack, sporting multiple connected rooms that all seem to loop back to each other and plenty of room to run around.

Origins
This area is inspired by an image used in one of wasteofblood's 1995 tracks of the name "2nd Floor." Most comparable is the image containing the Tox Box painting.

The music is a somber rendition of the "Inside Castle" theme from the vanilla game's OST. When the area is darkened, the music changes to that of Polygonal Chaos.
