  7. To dial: turn to the first number, change direction for the second, change direction again for the third, then confirm.

If you already know your code from a previous run, it won't necessarily work: read the file again.

🧩 The Final Puzzle (Marie's Doll)

Chapter: Spans both playthroughs

Where: A hidden challenge across two playthroughs. It isn't a trophy, but finishing it gives 20,000 CP early in run 2 for the Bonuses shop.

  1. Run 1, Processing (underground): when you pull the lever that reverses the belt, start a 15-minute timer and let about 115 bodies fall into the blood pool. Don't pull the far lever while you wait.
  2. Run 1, after the grinder: pull the lever by the elevator to drain the tank. The message must say a “ton” or a “torrent” of blood flowed out (“a lot” means you didn't wait long enough).
  3. Run 1, central hall: put Emily on the guard-office sofa and flush a toilet 8 times in the west wing restroom.
  4. Run 1, research facility emergency route: when the blood floods in, Marie's Doll is at the bottom of the stairs on the left. It goes into the item box for your next playthrough (it doesn't appear if you just reload an older save on the first run).
  5. Run 2, central hall: flush the toilet 8 times again, take Marie's Doll out of the item box, then carry Emily to the puzzle box in the lead researcher's office.
  6. Enter the four rows: Sun Sun Star · Sun Moon Star · Sun Moon Sun · Moon Star Moon. The game says you let the sweet pair hear the voice: check Challenges for the reward.

The 15-minute wait counts towards the in-game timer. We still finished run 1 in 3:50:40, under the 4-hour Speed Demon limit, but it doesn't leave much room.
