Other points of interest[edit]


  1. At the intersection with the jump pad to the corner life points, go to the north wall. Find the gear that is not moving and use it to push the wall forward, leading to a flamewall, twenty life points, and priest porridges. (sector 811)
  2. At the west side, enter a small corridor to a bazooka. You can open the third alcove to the north to get a drunk missile, a healing basin, and twenty-five life points. (sector 1116)
  3. At the ring hallway at the west side, open the east door and make your way to the room with the spike pillars. Go to the west wall and open the second wall from the top to get fifteen life points, a drunk missile, and a priest porridge. (sector 295)
  4. In the lava pit with floating platforms, head to the life point and open the wall to get a priest porridge and a firebomb. (sector 1267)
  5. Get the Dog Mode powerup and go to the hole at the west side to enter a secret zone where you can flip switches to find a secret warp switch. (sector 877)
  6. In the courtyard past the silver key door, head to the west field and press on the switch on the northwest column. Enter the room to the east and use the jump pad to go over the spikes to get a firebomb. (sector 1064)
  7. In the same courtyard, push a wall behind an empty fountain to find a bulletproof armor, thirty life points, and priest porridges. (sector 1070)
  8. At the iron key, open the wall near the fireball shooter to get a flamewall and ten life points. (sector 227)
  9. Use the Oscuro key and go to the northwest wall. Open it to find a passage to the secret exit. (sector 500)


Three bowls of priest porridge (Things 814 through 816) and one split missile launcher (817) in the small room east of the silver key hall have no flags set for any of the three difficulty classes, so they do not actually appear in the level.
