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...
*Voice audio is only in English

Cara, o que dizer sobre a SFB? Conheci eles com Tangle Tower, e descobri depois que eles haviam feito o meu jogo de infância preferido, e para minha felicidade eles haviam anunciado outro jogo do Grimoire, o Mermaid Mask. Então, o que dizer sobre o Mermaid Mask? Um jogo 10000/10, os caras conseguiram pegar o que era incrivel em Tangle, e melhorar mil vezes. A história é muito cativante do inicio ao fim, eu queria terminar logo e mal conseguia parar de jogar; os personagens incriveis. E você nunca desconfia do culpado, e nem do que realmente vai acontecer. Da para perceber o carinho que eles poe nesses jogos, e principalmente quando você le as anotações da galeria de arte, e digo, parabéns a todos que trabalharam no jogo, e nas artes. Gostaria que muitas pessoas conhecessem esse jogo pois VALEU CADA CENTAVO.
A very high quality point and click adventure game with very impressive voice acting and animations, and may I add some very good bad puns

It's clever, it's beautiful, it's hilarious - a knockout game so far!
Another point and click banger.
Felicia! When I catch you Felicia! Another great continuation in the series. This game really benefits from you having played the pervious one, Tangled Tower, however it's not necessary but there will be clear easter eggs you won't get. And the seemingly continuation of the mystery around Felicia is something I hope they keep going. There's many clever things to be done with her character and the mystery around her and I'm excited to see where the devs go with it should they choose too.
너무.. 너무 재밌어... ㅠㅠㅠ
This is one of the best "detective" games I have ever played. The writing, the voice acting, the gameplay loop, the animation and art....all 10's across the board
故事实在是令人唏嘘,通关后久久不能释怀。 海面之下压抑着人鱼哀恸的吼声,海面之下悬坠着漂流之船虚无的终点...
好玩
Hey did you know in the Odessy the sirens didnt tempt Odysseus with sex or whatever, but actually sang about knowledge of the future and the secrets of the universe, and only tying him to the mast kept him from destroying himself in pursuit of knowledge? Hahaha. Yeah.
