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...

Absolutely incredible. We want more!
I LOVED this game!!! I beat it in 3 days. Not because its easy, but because I didn't want to stop playing. Such a satisfying ending. I've already started replaying Tangle Tower because I need more!
It is one of the greatest accolades I can bestow to say this is a worthy sequel to Tangle Tower, that matches or slightly improves on it in every area. Maybe play TT first but definitely buy this if you have any interest in detective stories or deduction games.

I was happy to find that this game is yet another banger in the Detective Grimoire series. Everything about it is just so delightful, from the writing and voice acting, to the character designs and how they're animated. The puzzles are fairly difficult in general with a few that stumped me pretty well, and the core mystery of the story is very satisfying to piece together. 10/10
I feel like the developers get better with every release. The dialogues are amazing, designs of characters and the rooms are superb and everything in this, at first overwhelming story, just clicks into place perfectly. Every character felt interesting, the puzzles were great, the suspicions even better. I love that the puzzles keep evolving with each release (this time the 3D clues). The game balances whimsical tone and dark, haunting moments very well. The ending killers monologue was really strong and kept me spellbound to my screen. 10/10, would recommend, hopefully Sally and Grimoire got paid this time...
very good. Enjoyed it a lot
Awesome art, fun character, Great voice acting!!! The game is very fun and charming.
Story was great. Characters were fun. Humour was well written. Puzzles were good though I will say that the one in the cargo room was not that well designed.
Надел Хват шляпу, а она ему как раз
[Ранее я этот текст писал в другом месте, но надеюсь тут приживётся] [В основном отзыв художественный, чем технический] В машинном отделении субмарины вы видите торговца. Он утверждает, что его главный офис находиться в городе. В том месте трудно увидеть что-то не заколоченное досками. Его нынешний магазин полон покупателей, правда вырезанных их картона. Ярусом выше работает писатель. На поломанной пишущей машинке, гонящую одну и ту же исписанную страницу снова и снова. Прошёл "Маску Русалки" (Mermaid Mask), продолжение игры "Запутанная Башня" (Tangle Tower), и прошёл бы "Detective Grimoire", если бы его перевели на русский. Требует ли игра от вас знания Запутанной Башни? Желательно, но не обязательно. Первое впечатление "вау, это таже самое, но другое". По пути истории эта фраза менялась, в своих акцентах, но по итогу она заиграла странными огнями, и к ней добавилась "... и мне нравиться, что таков порядок вещей". Если в Запутанной Башни была трагедия семьи, в которой никто не виноват, то в Маске Русалке трагедия городка, в котором виноваты её жители. В Запутанной Башне - люди искренны. В Маске Русалки - лгут все. В обоих случаях - недоговаривают. И это является сюжетообразующим моментом. Ощущение, что после постмодернизма мы вернулись к классическому детективу. Возвращение к классике это не плохо, многие так делают со временем. Проще говоря: Таков порядок вещей.
