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...

After liking the previous two Detective Grimoire games a lot, I was looking forward to this one very much. And what can I say, I was not disappointed. Loved the story, the designs, the art, the animation, the excellent voice work, the incredible soundtrack and the puzzles and game mechanics for solving things. Absolutely delightful top to bottom. Despite a certain comment at the end I do hope the devs will end up making another one.
Je l'attendais depuis qu'il avait été annoncé, et il ne déçoit pas ! Quel plaisir de retrouver ces graphismes, ce voice acting et cette bande-son que je trouve même meilleure que dans Tangle Tower ! Les énigmes ne sont pas trop facile, mais réalisable tant qu'on prend le temps de se pencher dessus. Les easter egg sont délicieux, et sans rien spoiler, certains indices indiquent que quelque chose nous attend encore, et que nous n'avons pas finit d'enquêter sur les conséquences des actions des Fellows et des Remingtons. Un vrai plaisir. Je recommande pour tout les amateurs de jeux détectives !

One of the best adventure games I've ever played, excellent music, art design, story, everything. Thanks!
another smash from the inspector. Another case for Detective Grimoire and the lady we know as Sally. excited so far.
Amazing game! Builds on the previous one, but you don't need to play it first to enjoy this one. The puzzles were all really good, there were several good plot twists, and overall just very fun and satisfying to play. The characters are all hilarious in their own ways, and the art and animation are immaculate. I played it with my two daughters and we had a blast!
having played the prior installments in the series i had nothing but high expectations leading up to The Mermaid Mask's release, and after 2 and a half play throughs i can say without a doubt that i was absolutely blown away. the story way exceeded anything i couldve hoped for, and has left me speechless for almost 6 weeks, even playing it 2 times through im still finding more and more details in this masterpiece. the detective grimoire games are highly character driven, with the enjoyment coming from learning about the people inhabiting this world and unravelling the mystery together. the puzzle gameplay i found challenging enough to be really engaging, if you love beautiful art, animation, voice work and in depth well written characters, the mermaid mask and its predecessors are perfect for you!! i just truly love this franchise and i hope whoever plays can find as much joy as i have with these games!
I need to say that this is by far the best narrative game I've played to date, and maybe the best game period. It's oozing with care and love. I am a huge fan of the Detective Grimoire series and I considered Tangle Tower one of my favorite games since I first played it on my iPad several years ago (and I have a LOT of games). The Mermaid Mask, which I was beyond excited about for SO long, exceeded any and all very high expectations I had. It has all the charm of Tangle Tower times twenty with unbelievably beautiful art, including an amazing art book, a killer hook, fascinating and unique characters, and an exciting mystery. The ending is absolutely phenomenal and I love all the references/tie-ins to the previous games sprinkled throughout. This game truly holds a very special place in my heart and while more Detective Grimoire games would be incredible, I understand that it's an insane amount of work and series don't need to go on forever. I'd just as soon jump on any graphic novels or merch, but if this does remain a trilogy, it serves as an excellent trilogy as it stands. I would recommend this game to absolutely everybody, without question. At this price, you have nothing to lose and you'd be supporting a wonderful team.
I've been a fan of the series for years and this game is another banger!
Lá em 2010, conheci um jogo de mistério chamado Detective Grimoire (2007). 5 anos depois do primeiro jogo lançado na Steam da franquia nascida no site de jogos de navegador em 2 de janeiro de 2014 [i](hoje publicadora e distribuidora independente)[/i] Armor Games, Detective Grimoire e Sally tentavam trazer à tona a verdade por trás de uma terrível tragédia em Tangle Tower, lançado em 22 de outubro de 2019. Alguns anos depois, o seu sucesso em desvendar o caso os levou a Casúmulo [i](Silkwirm-on-sea no original em inglês)[/i] em [h1]The Mermaid Mask (lançado em 16 de julho de 2026)[/h1]onde eles precisam solucionar mais um caso improvável: A morte do Comandante Magnus Mortuga: morto em seu submarino, numa sala misteriosamente trancada. Tudo deste terceiro jogo é devidamente Maior do que em jogos anteriores, incluso a duração. Claro que tive alguns momentos que alargaram minha jogabilidade [i](decidi repetir o que fiz em Tangle Tower, e desliguei todas as dicas e tratei o jogo como se fosse um caso de verdade, anotando pistas relevantes em um caderninho)[/i], o jogo em si é terminado em algumas duas a quatro horas a mais do que o segundo jogo da franquia. Além da duração, as animações e os visuais são ainda mais espetaculares, com as pinturas exorbitantes de Catherine Unger sendo plano do fundo para as cenas e cenários do jogo; e talvez o maior criminoso deste jogo: o áudio. Trilhas sonoras orquestradas, atuações divertidíssimas (Steve Kearney no papel de Dirk Dansom foi um favorito meu junto da adorável Symmetry Silkmoth, por Justine Leah Hince) e um roteiro que, para a minha infelicidade, só poderia comentar sobre se soubesse que você já tenha jogado. O melhor que posso dizer da estória em The Mermaid Mask é comparar a obras de mistério em livro e filme, escapando da vil chance de acabar arruinando sua experiência, ao clássico de Sherlock Holmes "O Signo dos Quatro" por algumas razões... [spoiler] Este também evoca um pouquinho de Indiana Jones, mas creio que você só entenderia o que quero dizer com isto jogando você mesmo.[/spoiler] [h2]Concluindo[/h2] Jogos como os da franquia Detective Grimoire são os que, a cada 5-marromenos anos, me fazem lembrar porque que jogos indie são verdadeiramente onde a "indústria" dos jogos se sustenta, apesar das notícias não darem a eles o seu devido valor, salvo em repentinos casos de controvérsias ou vitriol. São jogos além de serem feitos por desenvolvedores, pessoas criativas, não criativas, escritores, gerentes de projetos, são (perdão pelo clichê) feitos e criados por pessoas de verdade. O momento que fui relembrado disto foi quando abri a Galeria de Arte (a costumeira recompensa ao chegar ao final da história nos jogos de Detective Grimoire) e li os comentários dos gamedev, comentando suas dificuldades, seus choros em terem que cortar coisas senão o jogo não lança. Comentários sobre comentários de seus personagens, opiniões, gostos. Tudo isso emerge à superfície da experiência de jogar um jogo que foi CRIADO por pessoas de verdade, não algoritmos de descoberta ou seguimentos de tendências. The Mermaid Mask é um marco histórico para a SFB Games, e desejo que apesar da ansiedade de "ter que passar por isso de novo" ter sido maior nesta edição (alguns comentários são encontrados sobre isso pelo jogo) os irmãos Vian e seus amigos algum dia recebam visões do além que os levem a mais uma nova aventura do melhor detetive sem chapéu que existe. Aqui em 2026, eu terminei um jogo de mistério chamado The Mermaid Mask.
I liked tangle tower and the mermaid mask does just as well if not better on all levels. Though some of the puzzles I feel as though could've been a little clearer, overall a super fun time that I'd recommend.
