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...

Graphic 5/5 Sound 4.5/5 Narrative 5/5 Gameplay 4/5 Overall 4.5/5 Story, atmosphere, and writing were all just as good as we expected going in. The artwork and character designs continue to be whimsical yet not childish. At some points the story seemed to make a logical jump, but nothing which was fundamentally detrimental to the plot. Our only complaint was that some puzzles were a little obtuse. There were no major bugs that we found, or performance issues. Of course, this is a point and click game, so this is not very demanding. Of the unique cast, Mortuga, the Captain, was our favorite. As the mystery evolves, you learn more and more about him and his drives. Sally, Grimoire's assistant also continues to be a favorite. Story and puzzle review below... warning: Spoilers will include prior games in the Detective Grimoire series, including Tangle Tower [spoiler]Worst puzzle? The corkboard, specifically because Mariana's diary does not show up again as a clue. I don't think we really had a favorite puzzle. Most were short enough to be straightforward. As for the ending, this feels very much a tragedy. Very few characters got what they wanted in the end, but most got what they "needed." The further the story goes, the more fantastical and horrific it becomes. It does eventually end on a note of "sometimes you don't know everything, and that's ok" I thought it was a nice touch that the girls from Tangle Tower show up at the end. It seems that the writers have a soft spot for pairs of young adult women who are trying to find their way in the world. [/spoiler]

My favourite game I played in 2026 so far! I was ultra excited for it after Tangle Tower. The mystery is intriguing and gripping, the atmosphere incredibly charming and overall it was a joy to play.
Jouez-y. Vous ne le regretterez pas.
Great detective game. Character designs are great and the voice acting is incredible. Only small gripe I had was the controller support being only okay, and there was one puzzle near the end that I had to use a mouse to complete, but used a controller for the entire rest of the game. Would definitely recommend.
Evolução absoluta da jornada de Grimoire e Sally. Que história boa!!!! Muito importante pontuar também como a ilustração se aprimora a cada jogo lançado, com o design de personagens sempre original, criativo e surpreendente. Recomendo muito pra quem gosta de investigação, e recomendo mais ainda que joguem os jogos anteriores antes pra enriquecer ainda mais a experiência.
As a fan of the series I was very happy with this release! The game includes an enjoyable cast, music, animations, story, and art! Would recommend the whole series, this game especially! :D
The writing is so good! One of the only games where I am not bored listening to NPCs rants.
A simple game you can't really fail that takes the charm, wit and whimsy of its predecessor and doubles down. An intriguing tale and a solid mystery! The soundtrack is once more just.... sublime. So good. The voice acting, the animations, EVERYTHING has so much love and detail poured into it. The two leads play fabulously off each other. Strong recommend for those looking for good writing, good characters, and intrigue in their games. For those looking for hard gameplay though? Eh.... Again, you can't fail in any meaningful way, or lock yourself out of basically anything, so even terrible gamers will have their path funneled into the end game. Gameplay itself is pretty light with some deduction puzzles, and some minigame puzzles. Nothing is particularly hard. TL;DR - Game is a masterclass in charm, a solidly written story and experience, and some decent gameplay tidbits in between.
This is a great game! Please play it, it's fun, beautiful and good time
