SFB Games returns with Detective Grimoire in The Mermaid Mask: hand-painted rooms, 3D evidence inspection and a haunting Budapest Art Orchestra score — a mostly flawless mystery with a few rough edges.
I bought The Mermaid Mask on launch day like an unashamed Grimoire addict, and it’s easy to see why the community is buzzing. SFB Games has taken the quirky point-and-click detective formula from Tangle Tower and turned up the ambition: 3D-inspectable clues, fully voiced characters and an orchestral soundtrack that actually gives the submarine a heartbeat. If you like slow-burn mysteries littered with eccentric suspects, atmospheric sets and jokes that land more often than they groan, this one’s built for you. It’s charming, occasionally melancholy, and frequently hilarious — a blend that kept me glued to my chair until the credits.
The Mermaid Mask is basically detective work in delightful costume: you point, you click, you question, and you rotate every suspicious doohickey until its secrets spill out. The core loop leans into exploration and conversation — poking around the Mortuga Submarine’s cramped corridors, questioning a gallery of wonderfully weird suspects, and piecing together timelines from dialogue and objects. Unlike old-school adventure games that rely on pixel hunts, here each clue is a fully realised 3D object you can examine from all angles; a stamp, a torn label, a coral-encrusted trinket suddenly feels like evidence with personality. Puzzles are woven into conversations and object inspection rather than shoe-horned minigames, so solving them rewards patience, observation and a willingness to re-listen to a line of dialogue. It’s a relaxed pace overall, but the stakes rise nicely as the plot threads tighten.
What sets The Mermaid Mask apart are the little mechanical flourishes SFB snuck in. There’s genuine freedom in the investigation: you can follow red herrings, double back on leads and sometimes reach conclusions in non-linear ways that affect how scenes play out. The game introduces clever inspection mechanics — rotating evidence, triggering 3D flashbacks, and toggling alternate views — which make deduction tactile and oddly satisfying. The cast is fully voiced (English only), and the voice work often elevates a throwaway line into a clue or a laugh. Fans of the series will also appreciate the callbacks to Tangle Tower and earlier entries; they don’t gate the story completely, but they add emotional weight if you’ve been along for the ride.
Visually, The Mermaid Mask is a love letter to stylised art direction: hand-painted backgrounds meet polished 3D models, and the camera frames each room like a tiny stage. The Budapest Art Orchestra score is a standout — sometimes eerie, sometimes sweeping, and often perfectly timed to nudge you toward curiosity. Performance on Windows and macOS has been solid in my runs; the game isn’t demanding, so it runs on modest machines. That said, players have reported a few hiccups: an odd fullscreen/save interaction that can confuse alt-tab behaviour, some achievement bugs and a few moments where voice volume felt lower than the music. These are rough edges rather than dealbreakers, and SFB’s polish elsewhere keeps the experience largely smooth.
The Mermaid Mask is a joyful, occasionally spooky detective game that marries witty writing with tactile investigative mechanics and gorgeous production values. Minor technical hiccups don’t overshadow a narrative and cast that will keep mystery lovers hooked for around ten hours. Buy it if you love character-driven puzzles, strong voice acting and atmospheric storytelling — and if you’re a Grimoire fan, consider it essential.
Players are overwhelmingly positive: praise centers on the writing, voice acting and the novel 3D inspection mechanics. Many reviews mention finishing the game in a single long sitting because the characters and story are so engaging, and longtime fans say it improves on Tangle Tower in its finale and emotional payoff. On the flip side, recurring complaints include a strange fullscreen/save interaction that can confuse some users, a handful of achievement bugs, and occasional audio balancing issues where dialogue feels quieter than the music. If you loved previous Detective Grimoire entries, reviewers agree this is a must-play; newcomers will find a polished, witty mystery with a handful of small technical niggles.
