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...

Gioco adorabile. La direzione artistica è semplicemente geniale e il mistero riesce davvero ad intrattenerti. La cura nell'estetica del gioco è ineccepibile. Mi piacerebbe davvero che continuassero ad uscire altri capitoli della saga, magari anche con uno sviluppo di trama orizzontale. Se proprio dovessi trovare una piccolissima pecca sarebbe la musica, a tratti era un po' troppo allegra e fuori tono per l'atmosfera da investigativo.
Incredible game that is very entertaining and worth the full price! Glad to see passionate devs making passion projects like this! The game is very approachable and that can be a good and a bad thing, I would love detective games to have a "hard" mode where they allow you to start a suspicion even if you don't have the required clues, so you have to think hard whether you actually have enough to accuse someone rather than the game notifying you

just phenomenal!! every step of this game had me wondering what could possibly have happened, and the pieces all fit so snugly together by the end. thoroughly compelling characters and stories, fantastic music and atmosphere, a properly disquieting environment that leaves you on the edge of your seat
Wonderful mystery-adventure game. Loved the voice-acting and how every character had a unique reaction for every clue; none of that "I don't care about this" repeat dialogue.
I absolutly love this game. The plot twist got me and my sister. I'll just say I love it again :'D
Absolutely fantastic sequel to Tangled Tower. What a fantastic cast of characters and such beautiful locations. Also really really funny Lots of really fun puzzle designs, only one gave a big issue but I was thinking about it in a different way. Overall highly recommend to anyone wanting a nice relaxing puzzle game with great characters and a fantastic story
Highly recommend this game especially for players who love a good old who-dunnit detective puzzle games. It was very easy to pick up and play - very charming game with beautiful artwork, amazing voice acting, and unique characters. Also love how they expanded further on the Detective Grimoire universe through this entry in the series. The story was very captivating with its mysteries and supernatural elements - it left me with some lingering questions by the end which left a deeper impression of this game for me. Especially with the third act which kept me hooked till the very end. The atmosphere was great and dare I say - the characters of this story felt more memorable than Tangle Tower's to me. The puzzles were fun and in my opinion, beginner friendly - as someone who doesn't play that many puzzle games. My only criticisms of this game is that you can't save your progress to different save files which can save time going through all the dialogue if you want to re-do a certain parts or go back to a certain chapter. Or in my case, getting all the achievements.... There were also times when I was looking through evidence that the song from the evidence menu kind of clashes and bleeds in with the theme song of the rooms you're in. Overall, enjoyed this game and hope the studio will keep making more of Detective Grimoire and Sally - I hope this isn't the last entry in the series.
Love the animation style and character design! The puzzles are fun and a good mixture of easier and harder to figure out. The voice acting is phenomenal! There are a lot of clues and a lot of dialogue options that come along with asking each suspect about all the clues but it made figuring out the story just the right amount of challenging. Absolutely recommend if you're looking for a chill puzzle/mystery game and appreciate the hard work of actual humans. This is art!!
I really enjoyed tangle tower and was eagerly anticipating this one. And it was worth the wait and delays - the mystery was engaging and I really wanted to know what was up with everyone at each point of the game. And the denouement was incredibly satisfying, I loved that moment just before where the evidence finally came together and I realised 'right it's THAT person, it couldn't be anyone else.' But what made that moment particularly good was how interesting and unique all the characters was, they all had depth and their own stories, so it was never super obvious (up until it was meant to be) exactly who the culprit would be. Y'know, the way a good mystery story is meant to be written. And the voice acting was great, the cast really added to everyone's personalities so well. I adored playing this and would highly recommend it to anyone hoping to sit down for a few hours with a good mystery.
