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...

a perfect follow up to Tangle Tower, completely lost track of time while playing.
탱글타워가 예쁜 똥이었다면 이건 예쁜 종이컵 정도... 이해는 전작보다 훨씬 낫지만 여전히 두루뭉술 솜사탕

Tout aussi bon, voire meilleur que le dernier titre de la série Comptez une bonne dizaine d'heures pour venir à bout de ce jeu d'une très bonne qualité générale Très accessible, avec une belle DA, des musiques vraiment à la hauteur et une intrigue bien ficelée L'histoire nous tient de bout en bout, le jeu sait garder une bonne dose de mystère à chaque étape de l'enquête, c'est une grande réussite à tous les niveaux Je recommande à tous types de joueurs
Tangle Tower ya era sobresaliente, mermaid mask hace todo mejor, sobre todo las animaciones se notan muchísimo más fluidas y el arte más pulido.
前作缠结塔收尾的速度太快了,总体可以算是好评,这一部是纯粹的好评,内容很丰富人物很可爱,证据还有3d建模了。没有鲁特里和奥博拉丁那么硬核推理,但绝对是优质的推理游戏。
A terrific whodunnit story, with solid voice acting, nice presentation. and a very witty dialogue I wholeheartedly recommend this
The best one in the series so far. Great work to the team. Was engaged the whole time and every story thread was interesting to me. Been a fan since the online game
Excellent art, animation, script, Voice acting. haven't finished the game yet (I left the game on for a night I'm not illiterate) but the story is interesting as well.
