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...

Immaculate, an improvement on the prior game in every aspect I can think of. Which, personally, is quite impressive given how tangle tower is still one of my all time favorites. 100% worth getting at full price and buying an extra for a friend. I eagerly await the sequel coming 2031 (trust).
I'll say it now. This was the best detective game I've ever played in my entire life. The story, the jokes, the design, the mystery, the lore, the music, the everything! All of it was set to the perfect nautical mystery. (I particularly liked the moment when the murderer did their somber "motive and backstory" speech. I felt like I really was there in that moment...truly amazing.) Let me tell you now: if you ever decide to do Grimoire 5? I will buy it day one, just to sink back into this wonderful world of mystery and intrigue. Bravo SFB Games. Bravo.

Played the tutorial. Is very good. Recommend.
Have you ever had your favorite part of a game be it's performances? That's a new one for me. A top shelf murder mystery. The writing, setting, animation, characters, dialogue, all perfect. It never once became overwhelming or confusing, and nothing overstayed it's welcome or got boring. If you're at all into detective games, do not miss this one.
Jogo muito bom! Ele é super imersivo e faz você se sentir dentro de uma série de mistério! Todos os personagens possuem designs e personalidades super interessantes! Adorei as referências do outro jogo, Tangle Tower!! Os puzzles são complicados na medida certa e é recompensador juntar todas as peças da história! Mal posso esperar para a próxima aventura de Grimoire e Sally!
This is hands-down one of the most awesome games I've ever played. The incredible writing, the fantastic animation and character designs, the fun puzzles and the thrill of piecing everything together- I was hooked by every little piece of this incredible experience. A fantastic mystery that I think everyone should get to experience!
Brilliant narrative investigation. I honestly recommend the whole series!
以下不包含剧透内容。 非常,非常完整的作品。作为一款推理游戏。难度上非常友好,有宝宝提示功能;就算不用,谜题本身的联想度也把握的不错,很少出现穷举法场景;游戏的剧情本身也算合理,个人认为最终谜题的揭开,虽然不算难,却并不会让人感到无聊,我觉得这是很难得的。 打完之后打开开发商一看,发现居然是十年前《haunt the house》的开发商,这可真是偶遇了。
Super great game
