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...

Endlessly charming, stylistic and incredible art, impeccable voice acting and a great point-and-click detective game with minor puzzles and SO. MUCH. DIALOGUE. Which never feels like a slog because of aforementioned great qualities. These are all things that the Detective Grimoire games have always had. The sequel does not shy away from being absolutely gorgeous, being funny with its duo of detectives, being emotional gripping with its suspects, and with its mysteries being captivating to explore and understand. Now with 3D models and a slightly longer game time (at around 10 hours). And so the question is: Does it improve upon the very obvious shortcoming of its predecessor, and for that matter, is it even necessary to play it, Tangle Tower, if it is? The answer is that it is absolutely better than Tangle Tower by a long shot, yet you still must play Tangle Tower before it. There are certain moments in this game that get your eyes wide open as it calls back to things in Tangle Tower that you simply can't understand nor enjoy without knowing. They aren't necessary per se to enjoy The Mermaid Mask, but you will lose a decent bit of emotional understanding without experiencing all the additional information from Tangle Tower. As for the improvements, this game has by far the best finale of all the Detective Grimoire games, which was the sticking point of Tangle Tower. The build up to its story is well-done, and it absolutely nails the climax too. Its culprit is by far the most well-executed of the three, and that's including Secret of the Swamp too, and the crime and motive definitely makes the most sense too. It's also reasonably solvable before the final act, although you wouldn't be able to figure out all of its mysteries so easily either, while also still resolving pretty much every single thing in the game. Aside from the lingering mystery beneath it all of course. There's room for another sequel here, but time will tell if SFB Games will make it. I can see that the Grimoire games take a LOT of effort, but by god I would be so happy to see the conclusion of this mysterious throughline building through them. A perfect Detective Grimoire game I would say.
[h1]This game and Tangle Tower...[/h1] They both have great way with words. Like each sentence spoken, be it in conversation or item description everything is done with feels and outstanding quality. They can read me milk bottle plaquette and I would be impressed. To have all voice actors put life into their characters, animators and sound designers creating such synch is just insanity to me. Then soundtrack starts and it turns into magic again. You may not like riddle/talk type of games but you have to appreciate the world they are creating and the means they use to achieve their goals. Soul is a thing that is really hard to find in modern games.
An extremely high quality mystery puzzle ish game. Great voice acting. Great animation. Great details. Good mystery. Truly loved. One of the characters has a pipe in their mouth at one part of their animation and the voice acting then actually sounds different as if speaking past a pipe. Thats madness. All in all a very enjoyable 10 hours.
可算发售了!激爽游玩中! 照例先骂一嘴翻译:不会翻可以不翻 第一次编辑(游玩时间:10小时)--------------------------- +作为grimoire系列的第三部正统作品,本作延续了前作(主要是tangled tower)优秀的美术风格和人设架构(包括但不限于:鲜明的人物,动听的音乐,以及与前二者相配合的、独具匠心的环境设计)。 +同样得以延续的是别具一格的幽默感,俏皮话,双关语,以及友善的挖苦打趣(“这幅画的内容是sally下了一个蛋”) +在创新方面,本作拓展了证物的互动维度,在小巧精炼的叙事结构中蕴含了更多信息。这可以看做对于前作证物系统的小小优化。 +同时,每个人物或多或少自己的“隐藏证物”。这些证物无法在第一轮环境搜索以及场景解密中获得,而是要通过对本人以及其他角色的问询对话开启。可以说这个设计增加了前期问询环节的层次感,并以此为已经在前作中熟悉这套游戏结构的老玩家们献上了更有厚度的剧本。 ?一件有些微妙的事是,作为在剧情和美术风格上都直接承接tangled tower的续作,本作(非常轻量级地)与单元性、独立性更强的前作不同,涉及了不止一个t.t.中登场的人物。他们大多数是以彩蛋出场,但作为一部(尽管推理强度非常低的)推理主题的作品,这些没有给出具体人物信息,而只是被提及姓名的背景人物,或许一定程度上增加了信息复杂度,让没有玩过前作的玩家无从区分彩蛋和线索。相比之下,t.t.对于前作角色的提及是更加隐晦的,又或者至少会附上一些人物信息。(当然作为系列的老玩家,能够看到庞大家族中其他人物的形象和去向,的确非常让人满足。)
Ждала эту игру больше года, потому что Tangle Tower понравилась мне невероятно сильно историей, стилем и механиками. Купила в первый час выхода и прошла за 6 часов. И что же я могу сказать? Это превзошло все мои ожидания! Сначала без спойлеров - разработчики улучшили уже хорошо работающие приемы и добавили новых - заметно, как игра, относительно прошлой работы, выглядит более целостно и интересно. Поработали над головоломками - на мой взгляд, ни одной похожей и ни одной душной не было. Это тебе не пятнашки) Дизайн персонажей, как и всегда, выше всяких похвал! Локации, музыка, измененное повествование в некоторые особенные моменты - полностью погружает в атмосферу. Если честно, не хотела отдавать 700р. (на скидках!!!) за короткую игрушку, но не пожалела ни разу!! Теперь со СПОЙЛЕРАМИ: - КАК ЖЕ Я испугалась, когда увидела в книжном шкафу эту чертову маску!!!!!!!! Ну очень жуткая вещь - Само преступление крайне интересно, в принципе выбор локации - субмарина с иллюзионистами и другими приколистами вообще не частый сеттинг. Сильно погружает в атмосферу, правда, не устану это повторять! - Сюжет и участь как Мортуги, так и Хвата меня правда тронули сильно. Я в целом очень люблю истории, где фигурирует не обычная жадность до власти или денег, а что-то большее... - Понравилось, что когда с Симметрией обсуждаешь других персонажей, есть небольшой интерактив с картами - В конце появление персонажей из Башни тоже очень порадовало) А также знакомые фамилии... По (возможным) минусам: - Как и в любой другой игре такого жанра, есть некоторые проблемы с тем, что ты уже догадался до чего-то, но пока не поговоришь о конкретном предмете - не активируешь диалог. Это нормально, в данном случае только один раз столкнулась с таким - Обязательно кому-то не понравится, что нет полноценной кнопки скипа головоломок! Но мне она не понадобилась, честно, все максимально понятно В целом, советую очень! Ну просто 100/10!
好看是真好看,视觉呈现水平一如既往的高,Sally比之前更可爱了(我跟你讲我就完全是为了Sally来玩这个游戏的)。场景和各种谜题都设计的精致无比,有种高质量动画剧集的感觉。 游戏系统见仁见智吧,我是玩起来感觉有强烈的压力,总觉得需要穷举一遍,实际上游戏似乎也挺鼓励这么玩的,毕竟这游戏很大一部分乐趣都来自于和角色们聊天,虽然配音和剧情都不错,但是挨个聊天说话真的很累啊,我甚至希望有人帮我全点一遍我直接看备忘就好了…… 推理的部分没有超出前作的范畴,基本上就是和所有人聊天,揭开每个人的个人秘密,整体复盘,解决终极秘密的这种流程。这套系统其实比起在推理更像再看推理小说,进入揭秘环节以后被系统推着走的感觉极强,很多细节也算不上严密,偶尔会让人觉得“这都行啊?”。 谜团设计的意外精简,真正核心的问题只有船长是怎么死的以及多年前在船长身上到底发生了什么这两件事,其他基本都是一些添头,感觉就是为了让玩家能够逐步解开谜题而设计的“教程”部分。还是那句话,被推着走的感觉太强。 船员们之间联系比较弱,没有太多可以深挖的故事,有不少看起来埋得很深的伏笔但完全没有要解释的意思。事到如今SFB好像已经懒得把故事讲清楚了,基本50%的角色故事都需要自己去脑补,环境和对白给出了暗示但实在是模棱两可,缠结塔也是这套,说好听点叫留白说难听点就是叙事能力差劲。 不过嘛,表演好看的话把推理什么扔到一边也不是不行,抛开漫长的搜证环节不谈,整体剧情的节奏和张力还是不错的,台词写的也很有趣,最后也算是个圆满结局,前作缠结塔里的角色也有登场,世界观拓展的越来越大,粉丝服务这方面做的是很好的。
Yeah. You can tell how and why this game took ages to make. It's magnificent. Easily my new favorite of the series, a really compelling mystery, amazing character writing and voice acting, and beautiful design and art. I found myself being wowed constantly, the 3D models, the music, the ~atmosphere~, I just couldn't put it down after I began. Of course as always, you don't need to play Tangle Tower to understand this game, but I would honestly recommend playing TT before this if only just to see how SFB Games has evolved. Genuinely of the the most memorable experiences I've had in a long time in regards to mystery games, cheers SFB, you knocked it out the park once again. 10/10 would love to play again.
This game was definitely well worth the wait! I first wishlisted this game close to when it was announced in December of 2023 and have been keeping a close eye on its development, especially since I was such a major fan of Tangle Tower after discovering it on Apple Arcade. As with Tangle Tower, the art direction, mystery, puzzles, and music are superb, with the new 3D models for the clues being absolutely stunning! I truly believe there is no other games like the Detective Grimoire series, all of them just ooze with pure passion, talent, and love for the medium of video games and point-and-click mysteries. An absolute must play and one of my favorite games of 2026. Hope to see Grimoire and Sally in another 7 years (or whatever SFB Games puts their passion into)!
探偵グリモワールシリーズ最新作 今作はロンチから日本語対応されています ありがたい…! 過去作とのつながりは一切ないですが、過去作を知ってるとニヤリとできる会話がちょいちょい出てきます。 ポイントアンドクリックの推理アドベンチャーゲームです 基本システムやぬるぬる動くアニメーション、フルボイスはそのままに、今作は証拠品を3Dモデルでぐりぐり動かして見れるようになったことでさらに推理探偵っぽさがパワーアップ 謎解きは相変わらず割としっかり聞き込みして文章とかも読まないと難しいです。 PVやSSもガッツリネタバレになってしまうので注意。 ちなみにロンチだとこのゲームの定価のお値段とほぼ同じくらいでシリーズ全作がそろったバンドルを買えちゃいます。めっちゃお得です!!!
Yes they did it! A few years after the great Tangle Tower, SFB Games manage to double down and make the fourth Detective Grimoire installment another great detective game! It's great to see those game evolve so much between each episode. Even though The Mermaid Mask juste looks from afar like "The successor to Tangle Tower", lots of subtle details have been added once again to make it even more nicer to play. Among which, the full modelisation in 3D of all clues, whuch definitely helps fo fully fledge out the "detective vibe". Art is there, music is there, I love how the story and characters manage to feel so unique and whimsy at the same time, without looking in any way like something that's been done before on any previous installment. It was a great to havethe opportunity to dwelve again into a Grimoire and Sally adventure, and have a new glimpse at the universe surrounding them. If SFB Games wanna try their luck at yet another installment, I will be up for it, as it seems the world has still so much to offer. Definitely a series that does not pale in comparison, and can stand proudly amongst the Ace Attorney and Golden Idol series to just name my favourites.
