  12. 12
    Defeat the Imps. A Spectre is in the slime pit.
  13. 13
    Facing north across the slime pit, find the misaligned wall segment. Quickly run into the pit and examine the wall to open a secret doorway.

  20. 20
    Near the entrance, step on the small crate surrounded by Health Bonuses.
  21. 21
    Turn around to see a large crate lower into the ground. Quickly get on it.

    When the crate raises, walk along other crates to grab the Red Key Card.
  23. 23
    From the Red Key crate, turn left to see a teleporter in the wall **[SECRET 3/3]**. Drop down and go through it.
