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...

Ein ganz wundervolles Point-And-Click Game. Man sieht die konsequente Weiterentwicklung aus den Vorgängern. Die Rätsel haben mir gut gefallen. Voice-Acting und Soundtrack fand ich exzellent. Bin wirklich traurig, dass ich es durchgespielt habe und hoffe sehr, dass es mindestens einen Nachfolger geben wird!
Really enjoyed the last title, glad to say that this one definitely doesn't disappoint. Looking forward to the next one.

INCREDIBLE game!!! From the backgrounds, to the music, to the characters and the story, and last but not least the puzzles, there is not a moment in the game that i did not like. It was a wonderful ride from the start to end, and i would BEG others to play this game if you're looking for a whimsical, fun and beautiful mystery game

Assim como em Tangle Tower, ainda sinto falta de mais interação com as pistas, no sentido de que você precisa seguir uma rota muito pré-definida que não te permite fazer conexões dentro de jogo antes dos personagens. No mais, gostei muito do jogo e achei a história muito interessante, bons personagens e ambientação.
a really solid murder mysery game, these guys have once again knocked it outta the park
Marvelous mystery! The voice acting is just as superb as in their previous games, and all the puzzles were fun!
Well done mystery, great music, chock full of voice acting (though there was one single line I ran across that seemed to be missing a take), and some absolutely incredible animation. Check it out!
J'avais beaucoup d'attente pour ce troisième opus (au vue de la qualité des 2 précédents), et je n'ai pas du tout été déçu. Je ne peux que le recommander !
A great mystery game on its own and an even better follow up to Tangle Tower. I love the art, animation, character designs, and dialogue a lot. The mystery was very cool and kept me questioning but never guessing in the dark. If I were to levy one single complaint, there were a lot of times I'd try to present evidence and it would say "we'll get to that" or "that's right but not quite what I'm looking for", and IMO it would have been better to write the dialogue or have branching dialogue so that if the player is right, they don't have to delay getting to the point they already figured out themself.
