I'm curious to know the relationship between the two pits, crushing pillars and three switches on the wall in this room. The switch on the right I understand opens the door to the next section of the map. But getting the pit floors to rise to reach the invulnerability and other goodies while avoiding setting off the pillars is still, years on, a mystery.
- The other two switches raise the goodies up to the level of the surrounding floor. You can't get to the goodies without setting off the pillars (unless the noclip bug occurs), because they are completely surrounded by the triggers for the pillars (orange rectangles). You can reach the switches without setting off the pillars, however, by walking parallel to the left wall of the entrance passage.
