Floor plan taken from the game's own geometry. 202 floor sections, about 19.5k units across. North is up.
Every upward-facing surface of the map, projected straight down — ramps and sloped cave floors included, ceilings not. Green diamonds are the ways out. Everything marked comes from the map's own event script. Stairs between levels and the secret walls a lever opens are not marked — neither is in the geometry.
