Engine Room Walkthrough

Walkthrough for the Engine Room in The Mermaid Mask: Godrik Gripp shop interview, moving compass puzzle, broken compass clue, and Illusion Theatre revisit hook.

The Engine Room sits to the right of Mariana Moon's Cargo Hold aboard the Mortuga Submarine—part shop, part workshop, and home to Godrik Gripp's eccentric wares. Into Indie Games' July 16 submarine part-two guide and 9Puz's launch-week route both treat this deck as the bridge between mid-deck financial puzzles and late Illusion Theatre threads: interview Gripp, solve the sliding moving compass puzzle, recover the broken compass, then return to Cargo Hold with Mariana's pipe recording revelation.

Gripp Shop Interview

  1. Trigger the encounter: Inspect three items in Gripp's hanging box until the shopkeeper peeks out and the interview menu opens—you cannot buy without currency, but examining stock counts as a formal encounter.
  2. Baseline questions: Ask about Gripp's inventory, the current clues in your Case File, and other crew members before pivoting to suspicion topics.
  3. Pipe follow-up: After Gripp dialogue, Sally references Mariana's pipe—return to Cargo Hold and present the pipe clue to learn it functions as a tape recorder.
  4. Symmetry thread: The recording implies Symmetry may be withholding information; revisit Bunk Room or Illusion Theatre when the Case File flags theatre hotspots.

Moving Compass Puzzle & Rewards

Beside Gripp's "Sale on Now" sign, four colored compasses slide vertically—each obeys a personality rule rather than magnetic north. KosGuides documents the mapping: yellow points away from others, purple refuses to participate, pink behaves like a clock, and red points toward the group. Solving unlocks a box containing the broken compass Gripp was repairing—a key inspectable for crew interviews and optional achievement progress. See our dedicated Engine Room compasses solution for placement screenshots.

Illusion Theatre Revisit Teaser

After the compass reward, Into Indie Games notes a return path to Illusion Theatre—push the hidden wall panel left of the stage to reveal an unsolved puzzle chamber you can defer until the Case File demands it. Public walkthroughs verified through July 20 still end shortly after this revisit hook; we do not publish unverified finale reconstruction or killer accusation order. Track Engine Room hotspots on Evidence Checklist before marathon interview sessions.
