The Mermaid Mask reddit: Demo Overview and Setting
With the release of the highly anticipated sequel to Tangle Tower, players on The Mermaid Mask reddit have been actively dissecting the atmospheric demo to uncover every hidden secret. The game reunites players with Detective Grimoire and Sally as they investigate a haunting locked-room murder aboard a mysterious submarine. The journey begins in the abandoned coastal ghost town of Silkworm-on-Sea, starting inside the run-down Stonetop Inn before transitioning to the eerie decks of the Moruga Submarine.
Video Highlights:
- Atmospheric Introduction: Exploring the abandoned Stonetop Inn and finding the initial case file.
- Submarine Boarding: Investigating the green-glowing buoy and entering the Moruga Submarine.
- Puzzle Solving: Walkthrough of the serpent cabinet dial puzzle in the Mess Hall.
- Crime Scene Investigation: Examining the Illusion Theater, the Stone Cauldron, and the victim's body.
The demo sets up a rich, atmospheric narrative. Silkworm-on-Sea appears entirely abandoned, with boarded-up windows, rotting furniture, and a looming lighthouse on the rocks. A mysterious green light emanating from a buoy chained to the submarine lures our detective duo inside, setting the stage for a classic whodunit with supernatural undertones.
Always examine environmental objects multiple times. Grimoire and Sally often provide additional lore, flavor text, or humorous banter on subsequent clicks.
Deciphering the Clues and Locked-Room Mystery
The core mystery revolves around the death of Captain Magnus Moruga, a 39-year-old captain who locked himself inside the submarine's Illusion Theater. When the door was forced open, his body was found lying on his back with a single clean cut across his throat. Oddly, no bladed weapon of any kind was found in the sealed room. This classic locked-room setup has sparked intense speculation on The Mermaid Mask reddit regarding whether a physical culprit or a supernatural entity is responsible.
To help you track the critical evidence found throughout the submarine, we have compiled a summary of the characters and the primary clues discovered during the demo.
| Character | Role | Key Observation |
|---|---|---|
| Detective Grimoire | Lead Investigator | Determined to solve the mystery despite having zero initial suspects. |
| Sally | Assistant Detective | Pragmatic, highly knowledgeable, and brought a mysterious novel along. |
| Magnus Moruga | Murder Victim | Former captain of the submarine; found dead in the locked Illusion Theater. |
| Captain Seafoam | Current Captain | Hired the detectives but remains locked inside the control room. |
Evaluating these characters reveals a tense power struggle aboard the submarine. The name of the vessel itself, "Seafoam," was crossed out and replaced with "Moruga," hinting at past mutiny or deep-seated resentment.
| Item Name | Location | Significance |
|---|---|---|
| Case File | Stonetop Inn Bar | Contains the initial report, crime scene photos, and Seafoam's signature. |
| Sally's Book | Sally's Inventory | "Hex of the Helmsman" by JD Weirman; contains hints about deep-sea horrors. |
| Sun Tablets | Mess Hall Cabinet | A brown glass bottle containing three varieties of mystery tablets. |
| Moon Vial | Illusion Theater | A smashed glass bottle that spilled a mysterious purple liquid on the floor. |
| Stargazing Girl | Illusion Theater | A piece of sailcloth marked with footprints and a circular imprint. |
| Stone Cauldron | Illusion Theater | An ancient cauldron with deep claw scratches on its sterile interior. |
The contrast between the pristine interior of the Stone Cauldron and its algae-covered exterior suggests it was submerged in seawater for a long time before being brought aboard and fitted with a heavy metal lid.
Pay close attention to the lock status of the Illusion Theater. The case file notes the room was forced open, meaning the killer had to escape before the door was breached, or they never left the room.
Step-by-Step Walkthrough: Solving the Serpent Cabinet Puzzle
The primary mechanical obstacle in the demo is the Serpent Cabinet Puzzle located in the Mess Hall. A large metal statue of a sea serpent houses a locked cabinet. To open it and claim the Sun Tablets inside, you must rotate four distinct dials into their correct mathematical arrangements. The puzzle relies on geometry and matching the number of sides on each shape to reach target sums.
The face of the cabinet displays two target numbers: 7 and 9. The lines connecting the dials indicate which shapes contribute to which sum.
Identify the Shapes and Sides
Each dial features a geometric shape with a specific number of sides. The triangle represents 3, the square represents 4, the pentagon represents 5, and the septagon represents 7.
Analyze the Connecting Lines
Observe how the paths connect the dials. The left side of the puzzle must sum up to 9, while the right side must sum up to 7.
Rotate the Dials to Align Values
Rotate the dials so that the mathematical values of the adjacent shapes add up perfectly. The combination requires placing the pentagon (5) and square (4) on the path leading to 9.
Complete the Sum for Seven
Align the remaining dials so that the square (4) and the triangle (3) connect to the path leading to the target sum of 7. The cabinet will click open automatically.
| Dial Position | Selected Shape | Value Contribution | Target Alignment |
|---|---|---|---|
| Top Left | Pentagon | 5 | Contributes to Left Sum (9) |
| Bottom Left | Square | 4 | Contributes to Left Sum (9) |
| Top Right | Square | 4 | Contributes to Right Sum (7) |
| Bottom Right | Triangle | 3 | Contributes to Right Sum (7) |
Solving this puzzle rewards you with the Sun Tablets. The bottle features a hand-drawn sun on the front and an onion-like drawing on the back, adding another layer to the submarine's medical or ritualistic secrets.
If the cabinet does not open immediately after aligning the shapes, double-check that the connecting lines are fully glowing, indicating a secure connection.
Submarine Exploration: Key Rooms and Secrets
The Moruga Submarine is a beautifully drawn but deeply unsettling vessel. It blends high-class Victorian luxury with industrial maritime machinery. During the demo, you can explore three primary areas, each containing subtle environmental clues that hint at the broader narrative of the full game.
The Parlor
- Victorian Design: Features a plush couch, lit candles, and classical music.
- The Her Painting: A massive portrait of a mysterious figure labeled "Her" with the Stonetop Inn emblem.
- Locked Control Room: Where Captain Seafoam is hiding, leaving taped instructions on the glass.
The Mess Hall
- Industrial Kitchen: Filled with pots, pans, and dead coral specimens.
- Serpent Statue: Houses the dial puzzle and features a taxidermied sea serpent body winding around the room.
- Mysterious Crayons: Red and blue crayons left on a table, hinting at a child's presence.
The Illusion Theater
- The Crime Scene: The cramped, curtained corridor where Captain Moruga was found dead.
- The Stone Cauldron: An ancient artifact with claw marks on the inside.
- The Moon Vial: Smashed purple liquid bottle matching the Sun Tablets' hand-drawn style.
The environmental storytelling in these rooms is incredibly dense. For instance, the "Her" painting in the Parlor smells distinctly of damp soil rather than oil paint, suggesting it was recently salvaged from the ruins of the Stonetop Inn and brought aboard for a specific purpose.
Notice the wooden stool knocked over in the Illusion Theater. It perfectly matches the rotting bar stools from the Stonetop Inn, proving that items are being actively moved between the inn and the submarine.
Lore Analysis, Theories, and Progression Checklist
The community on The Mermaid Mask reddit has formulated several compelling theories based on the demo's ending. The presence of the Stone Cauldron with claw scratches suggests that Captain Magnus Moruga did not die at the hands of a human. Instead, he may have unlocked the cauldron, releasing a clawed entity that slit his throat before escaping or dissolving back into the ocean.
Additionally, Sally's book, Hex of the Helmsman, written by JD Weirman and published by Kristen Kale, describes a helmsman facing "something terrible in the depths." This meta-narrative likely mirrors the actual events occurring aboard the Moruga.
| Environmental Clue | Visual Detail | Theory & Connection |
|---|---|---|
| Stonetop Inn Emblem | Stacked stones on the "Her" painting | Connects the abandoned inn's history directly to the submarine's crew. |
| Smashed Moon Vial | Smashed glass with purple residue | Represents a counter-agent or ritual liquid paired with the Sun Tablets. |
| Green Glowing Buoy | Creepy wooden face with green eyes | Acted as a beacon to lure Grimoire and Sally, indicating they were expected. |
| Crossed-out Name | "Seafoam" replaced with "Moruga" | Suggests a hostile takeover of the submarine prior to the murder. |
To ensure you have fully completed the demo and gathered all available context before the full game releases, use this progression checklist.
Demo Completion Milestones:
- Examine the case file at the Stonetop Inn bar
- Read the publisher's note and Chapter 1 of Sally's book
- Solve the Serpent Cabinet dial puzzle in the Mess Hall
- Obtain the Sun Tablets from the metal statue
- Inspect the smashed Moon Vial and the Stargazing Girl sailcloth

The transition from the colorful, whimsical environments of Tangle Tower to the dark, rain-slicked, and claustrophobic corridors of the Moruga Submarine marks a thrilling thematic shift for the series.
Keep an eye on the name "Baroness Fortuna" featured on the theater poster. This name connects to historical performances at the Stonetop Inn, suggesting the "Illusion Theater" aboard the sub is a recreation of a grander, long-lost stage.
Frequently Asked Questions
Q: Is there a way to enter the Control Room in the demo?
No, the Control Room remains locked throughout the demo. Captain Seafoam has taped a note to the window directing you to investigate the crime scene one floor down at the back of the submarine.
Q: What is the solution to the dial puzzle in the Mess Hall?
To solve the puzzle, rotate the dials so the shapes represent the numbers adding up to the targets. Align the pentagon (5) and square (4) to sum to 9 on the left, and the square (4) and triangle (3) to sum to 7 on the right.
Q: How does the community on The Mermaid Mask reddit view the locked-room mystery?
The consensus on The Mermaid Mask reddit is that the murder was committed by an entity trapped inside the Stone Cauldron. The claw marks inside the cauldron and the lack of a bladed weapon point toward a supernatural or non-human culprit.
Q: Are the Sun Tablets and Moon Vial connected?
Yes, both items feature matching hand-drawn labels of celestial bodies (the sun and the moon). The purple liquid from the Moon Vial and the mystery tablets likely play a key role in the submarine crew's survival or rituals.
