Detective Grimoire and Sally return to take on a new mystery on PC and consoles. Play a free demo available on Steam now!
Critically acclaimed creators of Crow Country and Snipperclips: Cut It Out, Together! SFB Games is delighted to announce that The Mermaid Mask – the thoroughly charming successor to the award-winning murder mystery title, Tangle Tower – is releasing this summer on PC and consoles.
A riotous follow-up to the beloved Tangle Tower, one of Apple Arcade’s top three most highly rated games of all time. It is the latest instalment of SFB Games’ much-loved Detective Grimoire series, which began as a flash game on Newgrounds in 2007. The Mermaid Mask is a witty, visually spectacular detective mystery that balances heavy themes with light-hearted humor.

Submerge yourself in the nautical beauty of the sprawling Mortuga Submarine, unlocking its many oddities and secrets. In the pitch-black waters beyond a long-abandoned fishing town, the enigmatic captain of the world’s strangest submarine has been murdered. Some say he was an immortal time-traveler. Others say he was a vampire, cursed to stay hidden beneath the waves forever.
Interrogate the sub’s suspicious occupants – each lovingly voice-acted and brought to life through expressive, hand-drawn 2D animation – and collect clues by solving satisfying puzzles designed to encourage curiosity, experimentation, and that ultimate “aha!” moment of discovery.

This new entry to the series sees the return of renowned voice actors, Edwyn Tiong (Loco Motive, Harold Halibut, Unavowed) and Amber Lee Connors (Jujustsu Kaizen, Demon Slayer, Dandadan, The Outer Worlds 2), to their roles as the endearing Detective Grimoire and his sardonic sidekick, Sally. Supported by an incredible cast of voice talent from gaming, anime, film, and radio – to be revealed soon.
“We’ve been working on The Mermaid Mask for a long time – never before have we poured so much love and care into a single project, and it’s become something quite remarkable.
In 2024, our survival-horror game Crow Country became a surprise hit, which diverted our attention a little longer than we’d initially intended (a good problem to have, as Crow Country was wonderfully well received).
We can’t wait to finally share The Mermaid Mask with players this year. There really is so much to discover in this game. It’s a great self-contained murder mystery for new players – while at the same time, for those people who are familiar with the series, particularly 2019’s Tangle Tower… you’re really not going to want to miss this.” – Adam Vian, Creative Director
