checked-no =>Level 4 Hidden Room: On floor 4, there is a mirror in the back of one room, reflecting David and the zombies. Before you kill the zombies, hop onto the box in the center, then press against the mirror to enter a secret room with a hidden pendant. =>Sextant Warp: In B2 while searching for the yellow orb, you'll eventually pass through a room with columns, a corpse and a scroll (it comes right before a room with two goblins and a floor switch button). In the corpse room, attack the columns in the right corner of the room. You'll smash them and reveal a switch, which opens a hidden passage to a room with the sextant. The sextant allows you to warp to any teleport room you've discovered at any time you'd like.
