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...

Maravilloso juego, fantásticos diseños (de personaje y habitaciones), increíble historia. Los puzzles son extremadamente originales y creativos, más de uno me hizo sentarme por varios minutos mirando y analizando qué pingo tenia que hacer. La trama es muy interesante y llena de pequeños chismes y datos que te atraen inmensamente. Me tardé 12hs (4hs más que Tangle Tower) pero es súper atrapante, la actuación es maravillosa, la animación es única y divertida, los diálogos son inteligentes y graciosos. Ojalá salgan muchas más ediciones de Grimoire y Sally, en mi casa son insta-buy!
Es hat sehr viel Spaß gemacht und die Synchronsprecher waren einfach fantastisch. Es hätten für mich noch mehr Rätsel sein dürfen, aber die muss man ja auch erst in die Geschichte einbauen können. Ich hoffe sehr, dass es noch weitere Teile geben wird. Das Detektiv-Duo ist einfach Klasse.

非常不错的剧情推理游戏,难度适中,画风优秀,人物刻画也很棒,主角团2人也很讨喜
Tangle Tower was great but had horrible ending due to, I guess, budget limitations This one doesn't have budget limitation, therefore it's one of the best Point & Click / Visual Novels Highly recommend
Love this thing, hope they make more!
Deceptively fun and quirky, while at the same time actually having some depth in terms of story and the mystery. Really enjoyed the voice acting. The animation sometimes felt a bit repetitive, but was also quite good overall. Loved the atmosphere. A particular bug meant we had to repeat some sections a couple of times but it was only a few minutes every time. Would really recommend both for fans of the previous game and for murder mystery fans in general!
I haven't yet finished the game and I probably won't for some time, because I don't want it to end. So I move very slowly, looking at everything, soaking everything in. I love it so much. I loved Tangle Tower with passion and Mermaid Mask is all I could've want from a sequel. Thank you.
I've loved this series for a while now both The Secret of the Swamp and Tangle Tower were fun games with compelling stories but holy cow The Mermaid Mask blows them both out of the water. This game is such a leap in quality way better graphics, way more characters and a much longer story. I see why there was such a gap between Tangle Tower and this game. 10/10 the story made me cry
A great game! I love everything about it: the storylines, the puzzles, the graphics, and the music. It has been a while since the Tangle Tower. This game has been in my wishlist for a year or so. It is such a great experience that I finished playing within five days. Can't wait for their next game!
