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...

Excellent story and well rounded characters and voice acting. Lots of fun.
Genuinely one of the most fun puzzle games I've ever played, all of the characters were so cute and interesting and the ending genuinely made me gasp. I also am a chronic dumb dumb so having puzzles that were mechanically easy to understand but with complex solutions made me feel very smart. Symmetry Silkmoth is the goat <3

Love these games, they are genuinely funny and compelling mysteries, with great music! The art style and animation is really charming too, and the puzzles are challenging but not too frustrating. Please check it out so that they can more of these (for my sake)
Endearing characters, fun music, and super detailed world. I caught on to a bunch of things, and clearly there was a ton more that I could have noticed.
Muy bueno
Fantastic game, SFB knocks it out the park again. The style and wit from tangled tower is present all over the game. I want a hundred more!
I want a giant mural of HER on my ceiling
I love that every game while being a theoretically standalone game that you can come into without feeling lost - not counting the murder mystery aspect as it's purposeful - each entry is building upon the universe which creates a really interesting setting. I reccomend buying the whole series and playing through it in chronological order.
A complete gem for puzzle point and clicks and a must play for fans of the genre. Funny, beautiful and fascinatingly haunting in a way that has lingered with me since finishing the first playthrough. I absolutely loved the art, the animated voice acting, the 3D clues and the gorgeous story with a cast of unique characters. You can feel the love and life that was poured into this game.
Loveddddd the art style of EVERYTHING. The contrast of the beautifully rendered backgrounds and the hand drawn highly stylistic characters was sooo good. Fully voice-acted, and WELL voice acted omg i haven't had so much fun listening to voice acting i think EVER. Voices, art, AND the mystery were all well thought out and well executed. Total recommendation if you want to play a great game.
