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...

Reviews
This is my first ever review for a game, and I can't think of a better game to leave a review for than The Mermaid Mask. Tangle tower was already a great game, and not knowing what quite to expect story wise going into this one was a treat. The claustrophobic nature of the Mortuga submarine, crammed with a great and colorful cast of characters to interview and press for details is a treat. A constant guessing game of who the murder is and how they done it all the way up to the end to find out the big question of, why ? If your looking for a more chill and laid back murder mystery to solve then definately give this one a go, or perhaps start with the very first game and work your way up to this one. Its certainly a great trilogy, and I look forward to them, and hope for, another one in the detective grimoire series If there is one single negative i could give for the game, one of the biggest issues. Its knowing the whole story on one play through, and not being able to feel the joy again at solving this mystery fresh. Though i'll probably come back to it again in a year or two, hopefully i will have forgotten enough to have a grand time again

跳了这么久票,原来是因为做嗨了。 游戏体量差不多是翻倍了;美术上从场景的堆砌物、人设的复杂程度和线索图片与建模都进行了升级;音乐上维持了水准,每个房间也都有自己的bgm,不过除了复用的Grimoire Theme和一个小游戏出现的海岛歌,没什么给人留下印象;每个角色都会对四十多条线索有不同的评论对话,哪怕是不关心的(甚至这种都很少)线索也会有两句,真的非常难得。 谜题方面,沼泽杀人有点敷衍,tangle tower为了艺术性牺牲掉了推理,本作至少是一个动机正常,手法正常的密室杀人了。虽然alibi和大部分人的追问内容还是令人难绷,不过本子明显是完善很多的。 可能是为了让人听完,人物调查对话都要双击(点一下暂停,再点一下跳转)来实现快速读对话,很奇怪的设计,体验并不好。此外正如画廊里说的,由于做嗨了,砍掉的部分有点多,这是在游玩中也能明显感受到的。游戏节奏也很差,分了七章,但是章节触发条件是与某个线索的互动,实际上就会导致线索全了对话差不多完了,剩下那几个互动的互动一次过一章,完全不知道这个分章有何意义,估计是和砍剧情一体两面的。有几个小游戏属于看一眼会做,但是完成游戏要折腾半天的,并不是那么愉快。 总体上为了艺术风格肯定是强烈推荐的,希望续作尽快端出来
отличная история, жду письма-инструкции
A surprisingly meaty little mystery with some stellar writing and performances. I was a little too stupid for some of the puzzles, but that's more of a me problem, admittedly.
an improvement on tangle tower (which was already a pretty good game) in nearly every way. ♥♥♥♥ the bilge, though.
Great story, amazing characters, interesting puzzles, need I say more?
명작작 명작 탱글타워보다 스토리는 훨씬 견고 해졌고 아이템이나 증거 찾는 과정에서 3d 도입한것도 너무 귀엽고 더 좋은 장치가 된거같아요. 캐릭터들 하나같이 다 매력적이고 배경이 진짜 절 미치게 합니다. 추리 게임 좋아하고 작화 특히 배경, 캐릭터 무브먼트 쩌는거 좋아한다? 당장 까세용. 게임 다 깨면 주는 아트워크도 저를 또 한번 미치게합니다. 돈 안아까워요. 귯
incredible!!!!
Plus complexe que ses deux prédécesseurs dans la saga Grimoire, j'ai beaucoup aimé revoir des noms qu'on avait déjà vu avant et comment ces noms sont impliqués dans l'histoire actuelle. Un peu plus complexe que les deux autres entrées, ça fait plaisir.
Waited years and it was perfect. I hope they make another.
