The Mermaid Mask: Building a Detective Story Around an Impossible Submarine Murder
A sealed submarine turns the classic locked room into an entire locked world.
Two Constraints at Once
Detective Grimoire and Sally reach the Mortuga Submarine after Captain Seafoam’s letter. Captain Magnus Mortuga is found dead in a locked room, while the submarine seals suspects away from the outside world.
This limits both space and possible culprits. Each clue can revise familiar rooms instead of merely unlocking another area.
Evidence as a System
SFB Games promises fully voiced interrogations, evidence gathering, contradictions, and manipulable 3D objects. These systems can form a loop: an object creates a question, an answer creates a contradiction, and the contradiction sends players back to the object.
Cozy and Unsettling
The official “cozy-creepy” description captures the tension. Colorful characters and humor soften the mood, but the impossible murder keeps every scene uncertain.
The Central Promise
Everything confirmed supports one mystery: Captain Mortuga, the locked room, a contained suspect pool, and inspectable evidence. The appeal is not mechanic count, but the density of connections.
