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...

nice
Jeu d'énigmes et d'enquête sympathique, le design des personnages et des lieux est très joli et originale, ce qui te donne envie d'en découvrir davantage sur eux. Bon jeu d'énigme avec une mécanique de gameplay et une da intéressante, je vais aller découvrir les autres aventures de Grimoire et Sally!

This game was a wonderful experience! I especially loooove the character designs and voice acting here. And the silly puns and character interactions for some of the things you investigate as well. The puzzles were pretty fun too. 10/10
Loved it
Another masterpiece from these guys. I was so excited to see there was a sequel coming and this fully lived up to my hopes. The gameplay, the art, the puzzles are all fantastic but the dialogue is where it really shines. I know this has literally just come out but I'm already hoping they'll be another one
Great ! The Art direction is still kicking, the plot is great, and the connection with the previous games is making me want to replay them ! If you like solving cases give it a go!
Well written murder mystery. Fun and unique puzzles that were challenging but intuitive. A compelling enough story that I finished it in one sitting. I really enjoy games made by this group of people and highly recommend as a fan of puzzle games.
Perfect game 10/10 amazing! Its like if you made the best game you possible could in a genre with genuine love and care
The artstyle and characters draw you in and then the story keeps you going, I didn't expect the twist but I for sure wasn't dissapointed! If this is your first time seeing these characters please go play Tangle Tower, just as fun with just as compelling of a story!!
As a big fan of the Detective Grimour series and having played the previous two games. I was excited for the new game coming out. I found this game to be really enjoyable and feels it has the weirdest character set in this game out of the entire franchise. With each character having their own little weird and unique quirks. One annoyance I did find is when you found an item that was related to a particular character, which would naturally offer up some additional information in previous games. Every character barely acknowledge it and tells you as little as possible (maybe for good reason). Which I found pretty annoying. Plus pretty much every puzzle requires critical thinking and no item offers up any kind of hint or solution, so 90% of the time you're going blindly into the puzzle. Often relying on a walk thought to find the various solution. But outside of all this it's a solid game and another great edition to the series, i also appreciated all the little nods and references to the older games.
