The Mermaid Mask
The game that proves a murder mystery lives or dies on how much you want to hear its characters talk.
A point-and-click murder mystery set in a submarine, featuring series detectives Grimoire and Sally solving the death of an enigmatic captain. Fully voiced, hand-painted art, original soundtrack. Story-driven, puzzle-light, dialogue-heavy—approximately 10 hours if you explore everything.
The Mermaid Mask succeeds because SFB Games understands that a detective mystery works through character banter and voice acting first—the puzzles and plot are permission to keep listening, not the main event.
Reviewers treat this as a series game, not a standalone—they compare it to Tangle Tower and earlier Detective Grimoire titles, and their satisfaction is partly relief that the formula still works at this quality level.
Voice acting and character writing are cited far more frequently than puzzle difficulty or mechanical innovation, marking these as the actual engine of player investment.
Multiple players describe finishing or near-finishing in one or two sittings, suggesting the game creates momentum that overrides the typical adventure-game pause pattern.
No recurring technical, design, or pacing complaints appear in the analyzed reviews. The pattern instead is consistency: players report engagement, satisfaction, and completion without friction. This is not absence of evidence—it reflects that the game reached its intended audience cleanly. The one potential barrier mentioned tangentially is the expectation-setting risk: marketing a murder mystery may draw players expecting Agatha Christie-level puzzle complexity rather than a story-focused experience.
See the game in motion.
A locked-room murder mystery aboard a submarine where Detective Grimoire and Sally investigate an eccentric captain's death. Features fully voiced cast, hand-painted environments, 3D modeled clues, original orchestral soundtrack, and mysterious suspects with hidden secrets.
A gorgeously animated detective game where the charm of the characters and the wit of the dialogue matter as much as solving the puzzle. Players emphasize voice acting, character dynamics, and humor as the core experience—the mystery and puzzles are excellent, but they're not why people are staying. Fans of the series describe it as a natural successor that doubles down on what worked before.
“Gameplay-wise this is more laid-back.”
“I was browsing the steam store this morning trying to find a game to play.”
“Gameplay is fun, the jokes are witty and i found myself cackling at some of the gags.”
“Top-notch voice acting, an oppressive atmosphere balanced out by a goofy sense of humor, some truly impressive puzzles...this one's got it all.”

Deep editorial analysis
Detective Grimoire games have always been dialogue-first experiences dressed up as puzzles. The Mermaid Mask leans fully into that priority. Reviewers consistently praise voice acting, character banter, and writing—which the official description mentions in passing. Puzzles appear in reviews far less often than you'd expect from a detective mystery, and when they do, the praise is measured: interesting, not challenging; reward intuition, not brainpower. One player notes the game is more laid-back than typical point-and-click fare. Another finished it in one sitting because of the characters, not despite the puzzles. The mystery plot itself matters—reviewers call it tight, intricate, well-handled—but it functions as scaffolding for a 10-hour conversation with people who are funny, weird, and well-voiced. The game works because the developers know the medium's real strength: you can make players care about a submarine full of suspects if you give each one a distinct voice and a joke that lands. Everything else is permission to continue listening.
