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...

续作灯塔案的商店页在哪里我找不到预约的地方啦急急急急急急!!!!!!
This game is AMAZING, the polish is so GOOD I am BEGGING SFB games to make a physical art book for this and Tangle Tower I need to EAT the art. Also I will be COUNTING THE DAYS until the soundtrack is available on Spotify, the music in these games is too good to not be in my daily rotation. I guess my point is PLAY THE GAME It's so good omggggGGGGG
在不计其数的闪退之后终于打完了,结局很喜欢我一直在笑,还有非常多和上一作的联系让人很高兴(但是我缺的Fltz这块在哪补啊?)全配音也很喜欢,比上一作感觉更热闹了,很好的平衡了欢乐和严肃的点。 虽然每次的死者外貌和性格都是我最喜欢这一点让人很难过!但是可以快点把下一作端上来吗plz? 求你了。
This is a fantastic piece of art, through and through. Creativity seeped through the pores of this game like salt seeps through old, weathered wooden planks. It embodies not just a silly nature that eases the tenses, but it embodies both the fascination, and horror, found in the depths of the sea. It includes characters who are all so different, so well loved in design and detail, you can't say you hate any of them, you really can't. All in, this game is a work of art in every sense of the word, and after many sleepless nights playing it, I can say I 100% suggest you play it.
So I opened this game, blinked, and 7 hours had passed. I don't think I've ever willingly done something for 7 hours straight without a break. And I'm only 50% of the way done with the game! This thing is incredibly charming- I find myself asking every single character about every item even if it's not relevant just to enjoy the dialogue. The animations and design are so beautiful, and I really appreciate the care put into each story. Can't wait to finish it! Definitely a worthy successor to tangle tower! I'm absolutely loving it so far
An incredible sequel to an already incredible game. It's fresh while still connecting tothe previous titles in a believable way. Absolutely worth the years spent in suspense over the details of it's release
This game is everything I hoped it would be and more. I can not emphasize enough how fun it was to discover the motivations of some characters and the killer. I was and still am enthralled by the game and its characters and story. This game was so well crafted, so charming, funny, and gripping. The wait has been more than worth while.
Masterfully designed, such a great game with very intricate storytelling.
An excellent follow-up to Tangle Tower. The mystery is engaging, and the developers trust you to tackle the mystery at your own pace and at your own direction. Puzzles are fun head-scratchers, I definitely needed hints here and there. (Also, you can play with zero hints, which I did until I would cave on the occasional puzzle I couldn't wrap my head around!) The real heart of the game is the unique oddball characters. Beautiful animation and fantastic voice acting for every character in the game. I love that the devs included a gallery with all of the concept art and various notes about the game's development. The series continues to be a gem. SFB will continue to be an instant buy for me!
还是tangle tower熟悉的配料,侦探双簧组,诗歌判词,奇奇怪怪的人物。 虽然气氛灵异,但基本上都是科学解释。过程充满张力和悬念,很吸引人,解谜没有任何难为人的地方,案子也比前作更有说服力。但有些一直困惑我的问题始终没得到解答,以至于最后通关还以为自己漏了什么线索,没打出真结局…
