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...

its so peak...................
Very satisfying. Even better characters than before, plus the excellent dialogue and voice acting that I expected from this series. I was smiling through most of it and laughed out loud at a few really solid jokes. Like its predecessor, some of the reasoning and solutions feel awkward and require significant suspension of disbelief. But unlike Tangle Tower, none of that was enough to sour me on the game. The mystery here was good enough. The story surrounding it was better. The characters and voice acting, though, are PHENOMENAL and worth the price of admission. I want more. They should do an animated series, like a modern-day Scooby Doo. I'd watch.

Pros: -Dreamlike art, surprisingly colorful and varied for the inside of a submarine. -Spooky music. -The quirkiest cast of characters yet in this series. I didn't want any of them to be the murderer. -An unlimited supply of witty banter between Grimoire and Sally. -A wide variety of fun mini-puzzles. -Pairs well with recently having read 20,000 Leagues Under the Sea. Cons: -Similarly to Tangle Tower, the mystery is solved by an increasingly farfetched series of reveals, rather than logical deduction. I wish the developers would go back to the original Detective Grimoire where it was actually possible to guess the killer. I hope the part where an author is struggling to write a sequel under the pressure of past success is not autobiographical, because I'll always want more entries...
9/10. I waited for this game for so long, that I remember when it went by a different name. And the end result is SO good, that it was worth every single second of waiting. I love every SFB game, but this might genuinely be their best. Hope Grimoire and Sally come back someday!
Fun characters, puzzles, and story as always. Loved the va performances! Big fan of the art gallery at the end to learn more about the design process.
Absolutely love this game it's such a gem! I only discovered this game because I saw Gab playing it as well as the others from the series. I honestly wished I found it sooner it's right up my alley! I do hope the developers make another game to follow this one up! The story, the characters, and the world are so well built plus I love that the developers actually include myths and monsters rather than pulling a scooby doo like Nancy Drew. 10/10! <3
HIGHLY recommend for anyone that loves mystery with sharp witty dialogue in a wonderful world with some mysticism in it. This game is a VERY strong upgrade from Tangle Tower: The dialogue feels even punchier, the characters feel even more engaging and complex, the new 3D clues and other system changes are MASSIVE upgrades. This game sucks you right in, and builds you slowly towards that incredible peak as the climax of the story moves closer, then takes you EVEN HIGHER. They also managed to deal with my biggest gripes in Tangle Tower which is that we FINALLY get to see the characters interact with each other! And also the mystery is much more difficult to solve! and the multitiudes of bug fixes!!! and I utterly ADORE the ONGOING mysteries from the previous detective grimoire games, which I now realise means they are playing the LONG game with this and I am SO excited. The way they built upon and added to their already existing world makes everything so SO satisfying and gets your heart pumping like nothing else. If I HAD to give my minor nitpicks, it's the missable achivements (as a trophy hunter), and that the "mystery solving logic puzzles" still feel like you can guess-and-check. Still waiting for that chapter select too... Buuuut that's it. PLEASE play this game, even if you haven't tried their previous games.
Very impressive and very fun mystery point-and-click game. I can't believe it's 100% voice acted, you rarely see that much dedication put into the presentation of a game like this.
Another absolute Gem!
