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...

10/10 Great mystery, great fun!
This game is really good and is fun to play from beginning to end. They really stepped up their game from their last entry, and I would love to see more from this studio!
看到制作组新作技术力又提高了真的很高兴,角色塑造和对话也还是原来的味道,每个角色的动作更多更流畅,甚至还有多段动画演出,过场使用3D人偶演示也让事件发展脉络更加清晰易懂了,期待还能有下一部作品!角色里面最喜欢Symmetry,希望后续作品还会作为彩蛋和Sinthia再次出场

I love this series QAQQQQ. I almost cried for the ending... love every characters, which makes this tough but also unforgettable... I was surprised there is such connections with the characters in Tangle Tower. Can't wait for the next one, there are many mysteries still to be revealed by Grimoire and Sally!
One word: Dirk Play the game, you won't regret it. I played this game with my two sisters and we had a blast. The characters are well written, the motivations are fleshed out well, and the animations are well crafted and hilarious. My sister is a writer and thought Wirman was spot on.
It was the best detective game i have ever played... I was waiting for it for very long time and it was really worth it. It was precious. Puzzles weren't too hard but also they requiered a little thinking. Character design - simply awesome. This game is a masterpiece. Detective Grimoire, Tangle Tower and Mermaid Mask are simply my favorite puzzle games EVER
I think this game is the strongest in the series so far. Loved all of the characters and you can just feel the amount of passion and effort that was put into every aspect of the game. Particularly loved the music. Had trouble with a few puzzles but it was always satisfying when I figured it out.
so fun and detialed
처음엔 모르는 것 투성이겠지만 마지막엔 전부 알게 됩니다
One of the best storytelling experiences I’ve had in a mystery detective game. The story is complex yet clearly explained, with no plot or logic loopholes. Some details may initially seem irrelevant, but they all come together beautifully in the end. The puzzles are fun to solve and feel original. Overall, it’s a wonderful experience. Perfect game for beginners to mystery games—highly recommended !!!
