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...

If I had a nickel for every amazing mermaid themed murder mystery game I played this year, I'd have two nickels which isn't a lot but man am I glad it happened twice.
比起缠结塔,这一作讲了一个更加完整的故事,有更多的3D演出和更加便捷的功能,包括梳理已询问物品和人物的文字和图标提示,以及整体进度小结等。延续了前作的优良传统,并且有了更人性化的提示系统防止卡关,并且在不剧透的情况下有更顺滑的探索体验。小游戏的类型变多了,但是游戏理解难度的极差比较大,有几个小游戏需要对一下电波。 这次没烂尾。 最终阶段的连续解谜和信息梳理的爽感很高,但因为我纸笔记录了很多东西,发现不少小细节没有填坑,估计是重要性不高,不想放进主线叙事里。(但是有几个事情真的想进一步了解真相啊怎么夹断了!) 总结起来就是犟人遇上犟人,大伙都别想好过的故事,奇幻中带着写实,写实中掺着奇幻。 文本扎实,对话从不无聊,没有任何流水账的感觉,像是看了一部完整的侦探电影。 感谢带来一款体验优秀的新作,期待接下来的故事。 我的整体体验大约7-8小时(中间挂机做饭去了),因为有自动存档系统,有几个需要关注细节的小成就漏掉了,理论上一周目可白金。

I really loved it! I waited for this for years, because Tangle Tower is one of my favourite games. I actually think this game has surpassed it. I loved the story, the storytelling, the visuals, the music, everything. I would highly recommend playing Detective Grimoire and Tangle Tower before playing this game, since there are quite some references.
I just finished the game with a friend and it was AMAZING!!! Tangle Tower was already a great game and this was more than I dreamed of and more.
Muito bão Não tem um cachorro
Very fun murder mystery game! The art and character design is mainly what pulled me in and then i stayed for the story. The puzzles throughout were fun (though at times challenging; looking at you corkboard puzzle) and helped give the player a break between constant character interactions. The story itself was very intriguing and had me guessing right until the final reveal. Several characters are suspicious and no one particularly stands out as the obvious culprit until the final chapter of the game. The storytelling and twist were phenomenal though and left me feeling satisfied but also wanting to know even more. I also really appreciated the subtle hints and foreshadowing given throughout the game as to different characters being suspicious and how they're connected to one another. The relationships between the different characters was my favorite thing to learn about and uncover even over the mystery. I still wish that family tree of Silkwirm had been explained in detail so I could know more about the people and the town. This game is supremely dialogue heavy which is typical of visual novel games but often you're in the same spot interacting with one character for long periods as you show them clues. Exploration and character grilling was less intertwined and reliant on triggering specific dialogue from a character to allow you to get an item and more mutually exclusive mechanics. Some instances like this did happen but almost all clues are found by doing puzzles and clicking on things in different rooms. I would have preferred for more interactions where characters provide clues or context that was missing to find clues like the clues you find in the last chapters of the game. Also some more slight variety on character location throughout the different chapters of the game. The instances where the cast meet together in rooms were very fun and interesting and I simply wish it had happened more to give a bit more of a sense of progress. I think part of my struggle was that I often ignored the game when it prompted me to go talk to a different character about new information or check another room but I often felt stuck in one spot not moving for long periods of time while playing. At times I was showing clues and listening to character dialogue for almost 30 minutes without a break and in the end felt like I had only progressed a little bit towards solving the mystery. I can't say it was a fault of the game entirely though because I often play games with a fear of leaving an area without exploring everything and talking to everyone first. So if you do play I would encourage swapping between suspects and looking for clues much more often than I did and don't get stuck in one spot too long. Overall I supremely supremely enjoyed this game!! The mystery and the cast were extremely entertaining and I highly recommend this game for murder mystery and visual novel fans. I hope that SFB games has enough success to continue this series and that I will be seeing Detective Grimoire and Sally again in another mystery again in the future!
Okay, I'm now obsessed with detective games now.
不带恐怖要素的点击解谜,这就是我需要的 美术风格很棒,配音也很可爱
Played the previous two games and they just keep getting better. The writing, the voice acting and the beautiful graphics are superb. Would have liked to have played on iOS or Android with a touch screen but couldn't wait to play the next instalment. Hoping there is a 4th game coming!
Very fun! I especially love the dialogue, clicked on everything i could just in case there was something for Sally and Grimoire to comment on, didn't want to miss any. Everyone should definitely play. (some achievements will lock near the end and the only way to get them is a new save, so just watch for that if that's important to you)
