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

It was a long wait, but the game was worth it. I played the previous installments with my 10yo kid and he insisted on putting The Mermaid Mask on the wishlist. So we did, and regularly checked on the release date. At last we had a free weekend together, and cracked the game (3 achievements missing...) in 16 hours. The story was really great, everything logically connected, every character with unique quirks and traits. There was a stage where we had to ask everyone about everything, because sometimes the comments pushing the story forward were a bit unexpected. But once all clues were unlocked, in the endgame, all started to fall into place in the most satisfying and logical way, leaving no loose ends. Really wholesome and touching experience, for something disguised as a "detective game". My kid already asks about the next part!

很棒的推理游戏!比前作《缠结塔》更好玩,整个故事的逻辑和完整性好像也优秀得多。关键还有好听的全语音、夯爆的美术、引人入胜的音乐、上大分的本地化、无处不在的细节、各种主角的小幽默,整个游戏流程非常令人享受。谜题方面比较简单,推理部分的提示做得也不错,实在不行直接穷举也没有什么惩罚(甚至有一些意料之外的语音之类的)。强烈推荐给侦探游戏爱好玩家。 就是希望能给手柄操作再优化一下,倒是能理解鼠标模式很多情况下还得用,但是至少可以给固定按钮分配一些按键之类的。 9.5/10
Fantastic art and voice acting, compelling mystery with multiple intertwined storylines. You can tell that this game is an act of love by the quality in every bit of it. Lovely making of art so you can see the process as well. Highly recommend
Just had my human perspective permanently and irrevocably shifted but hey what's new
I wanted to write a whole essay of a review, but I had to stop myself. This is downright one of the best written and best made adventure games of the last decade. I am not kidding. The characters are amazing, the writing is absolutely top notch, with a level of depth and content I have rarely seen before. The whole game is constantly intriguing without being filled with pointless red herrings or false leads. I've played the previous two games in the series as well, and each one has been better than the last. Huge congratulations to the dev team!

Absolutely worth the wait. I LOVED IT SO MUCH! The voiceovers, perfect. Character designs, perfect. The mystery? Perfect. Once more Detective Grimoire and Sally got me hooked to another mystery. I'm glad I saw their funny yet clever puns and dynamic again while trying to choose suspects to frame as the murderer.
