About
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-traveller. Others say he was a vampire, cursed to stay hidden beneath the waves forever...
Found alone in a locked room, with only an ancient stone cauldron to suggest how he might have died, it's up to Detective Grimoire and Sally to piece together what really happened. Was it a curse, released from the cauldron? One of the submarine's eccentric crew? Or does the bizarre truth run even deeper...
• Every clue is a fully realised 3D object waiting to be examined for hidden secrets
• Grimoire and Sally are back, and joined by a fully voiced cast of mysterious suspects
• A hauntingly beautiful original soundtrack performed by the Budapest Art Orchestra
• Explore every hand-painted inch of The Mortuga Submarine, where not all is as it seems...

As a big fan of Tangle Tower, I was really excited to play The Mermaid Mask, and it did not disappoint. Everything about this game - the story, atmosphere, voice acting, animations, artwork, music - is on point. The puzzles are engaging and some a little challenging, but very fun to do! And the humor is excellent. Plus, I feel like this game leaned more into the creepiness, which I loved. They say how hard it is to make a sequel to a beloved game, and that they only hope it stands up to the original. And the thing is, I think they more than accomplished it! This feels like an incredible sequel that only builds on what was given to us in Tangle Tower, if not made to be even better. I mean, my playtime in this game is pretty much double what it took to 100% Tangle Tower. Plus, the story is so good! I was hooked until the very end, and everything also pieced together like a perfect puzzle. I am very impressed and can see myself playing it again later. I'm really hoping SFB makes more games in this series so we can continue to get cozy, fun, and highly atmospheric murder mysteries!

[h1]A Humorous and Relaxing Detective Game[/h1] Wonderful diverse cast of characters and voice acting, a lovely cartoony art style, a bucketload of charm, and wonderful duo-protagonists, discussing everything as we go along. This is not the kind of game that dominates your steam replay, but it can contest for one of the best entertainment-per-hour, if you enjoy the feel of point and click adventure games. This is my first entry into the series, as I bought it due to keeping an eye on upcoming games that might fit my interests, and the style plus being on a submarine hooked me in. The game’s quality ensures that I will check out the previous titles, but it is not needed to follow any of the plot. I was only reminded of it because they came with the kind of lines that either hinted at previous adventures or a “noodle incident” sort of situation. [i](For those that do not know, “noodle incident” is a meaningful incident in the past that is never fully explained, and their context only shown by the way characters react to its mention.)[/i] Honestly, I adore most about this, as it strikes a lovely comedic tone through the eccentrics cast and banter, while still incorporating serious elements and a surprise ending. The protagonists came off as smart, at least to me, as they gathered all the evidence before jumping to conclusions. Along with the game giving overall hints, if you are unsure where to go to progress. Any puzzles not dealing with detective mystery could also be solved with logic on the thing itself rather than wondering if you needed to pick up objects from other places first. Still early in the year, but this is deservingly one of the gems of 2026 for me.
很喜欢Grimoire和Sally组合的这两作,非常迷人、出色的画风,每个角色的台词设计和配音也如此契合。 玩这系列特别像来了场舒适的心灵按摩,那种感受大概就是本作里说的——一次“和神秘主义的擦肩而过”。 请一定要有下一作啊 I humbly implore you.
A splendid use of female property and labour: fully funding one incel loser’s search for Mermaid Mummy and his revenge on the man who got the woman, the adventure and the legend. The inn came from Felicia. The deeds came from Felicia. The key came from Felicia. The submarine came from Sinthia’s mother. Gripp's magnificent personal contribution appears to consist of some engineering, fraud, murder, and a heroic quantity of self-pity. You guessed it: he ends up with the mummy, as the one man in all humanity apparently worthy of being chosen, plus some of the most lavish scenes this game’s scale can provide, lovingly supplied by his developer bros. It is genuinely impossible to imagine who could Gripp possibly be a projection of? There are simply no clues. Very subtle. Over a decade ago, the same creator made a mermaid-and-cauldron comic where the women were allowed to speak, act, make decisions and help one another. Apparently artistic development has since transformed them into dead girlfriends, stolen property, emotional support staff and enormous silent prizes for miserable men. Progress, one supposes. Most of the characters—and, apparently, the entire very white creative team behind them—eventually agree that the Black girl is the one person who simply cannot be allowed to keep her power. This is all for her own good, naturally. A touching little exercise in community-led disenfranchisement. The developers also periodically remind us how difficult the whole thing was to make, as if producing a paid commercial product were a personal favour to the audience. One might have assumed the purchase price covered the labour. Apparently the customer was also expected to provide emotional support. Perhaps the creators should return to a few private playthroughs of Indiana Jones and Mafia, where they can imagine themselves as the alpha in peace and stop asking women to finance, mother, inspire, console and spiritually reward every male crisis. Or, better yet, simply stop making the next one. Anyway, lovely art, excellent voice acting, charming puzzles. Narratively, it feels like someone accidentally left his private Chad grievance journal in the game files.
This game is so lovingly crafted, so beautifully polished, and so cleverly structured. I have been following this team since they released Detective Grimoire and seeing the developers hone their style is such a great feeling. The final sequence had me enthralled the whole way through and it was striking how this game somehow managed to balance wacky and lighthearted moments with some of its darker themes. I could not suggest this game more and if you end up enjoying this I implore you to check out their other games.
The third game in the [i]Detective Grimoire[/i] series is another step up. I played the first two games out of order, [i]Tangle Tower[/i] last year and the first game just a few weeks ago to get ready for this one (and because I didn't want to go back two technology evolutions). I think that was the right choice, because [i]The Mermaid Mask[/i] is such a treat on the eyes (animation) and ears (voice acting and music) that the first game looks quite dated in comparison. But I digress. I love the characters in this game. While the second game had good characters for the most part, too, here I switched my favourite character multiple times upon meeting a new inhabitant of the submarine. I ended up enjoying the performance of the eventual culprit the most (especially once the plot was revealed and the character shifted), but 2-3 other side characters were close behind and the rest not far off. Most of all, however, I again tremendously enjoyed the performance, interaction and dynamics of Grimoire and Sally -- just an outstanding duo were both are allowed to be goofy or smart depending on the subject matter. I also think the story were superior to the prequel. Just a bit more mysterious and interesting to me, underlined by the atmospheric music and the claustrophobic setting. The story progression also seems to be a bit more tidy, with a brief introduction, a long (but entertaining and engaging) "gathering clues" section and a quick pace towards the ending where both performances and story revelations came together to provide a peak finale that answered all questions and still managed to be mysterious, true to the setting. Loved it. Oh, and I also enjoyed the 3D animations. Apparently developing a small retro 3D Silent Hill-like has inspired the team and it was inserted well. Overall this was a great game. Once every character was introduced and the story picked up steam, I couldn't stop playing until I saw the ending. And on a final note: the development gallery after beating the game is charming and interesting, what a nice bonus on top of the great ending. Thumbs up all the way.
I really liked playing this game. The writing is wonderful, the art is great and the mystery is intriguing. I had a lot of fun investigating and love how much there is to discover. Also the voice acting is fabulous, the humour is fitting, the characters are fantastic, the gameplay feels fresh and I could go on and on. I feel like there was a lot of love poured into making this game. I hope the people behind it can continue working on a sequel if they want to. And it's also great for playing together!
Really, really enjoyable. SFB has clearly found their winning formula, now I'm just hoping there's less time between MM and a new release than their was between MM and Tangle Tower. Speaking of, I might be in the minority of people that actually enjoyed Tangle Tower more - I thought the shorter length made it feel a lot more dense and I enjoyed the premise as well as late-game reveals more. That said, it's not an indictment against MM - the steak is juicy and the lobster is buttery
This game is one of few point and click games that I could play over and over again without growing tired of it; the art is impeccable and the sound design and music to accompany it creates such an immersive world and adds to the depth of it's characters. Speaking of the characters, I simply couldn't get enough of them; each one was so jam packed with personality it made listening to all of their dialogue so worthwhile and borderline addicting. To put it simply there is no way you could hate this game, the arcs are too tight, each chapter leads to the next - beginning, middle, end - and bang. Not a line wasted.
