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...
*Voice audio is only in English

Я увидел новость что вышла некая "The Mermaid Mask". Провалился, посмотрел, интересно и красиво, увидел что ранее студия выпустила еще одну игру со своим названием и таким же стилем рисовки"Tangle Tower". Думаю "ну окей", я давно в такое не играл и выглядит все очень красиво и заинтересовали моменты с "Детективной дедукцией. Сразу купил обе части, вот прям чувствовал, что пройду обе. Так и вышло. Прошел первую "Tangle Tower", по эмоциям в конце оказалась сильнее из за последней фразы от Поппи. Отличный сюжет и крутые персонажи. А еще мне ближе тематика "Дело об убийстве в особняке". Музыка во время загадок лучше чем в "The Mermaid Mask". И вот мы здесь, я прошел "The Mermaid Mask" и да, это все еще круто. В плане игровых механик стала более продуманной чем предыдущая игра. Больше интерактива и неочевидные взаимодействия с окружением. Сюжет такой же отличный, персонажи хорошие. ИЗ МИНУСОВ субъективно • Персонажи слегка хуже чем "круто" • Музыка во время загадок была лучше в "Башне" • Думал можно будет взаимодействовать с уликами вне диалог об этой улике Игру советую даже тем кто не любит квесты-кликеры. Студия молодцы и...я теперь хочу еще одну игру из серии. Мир который создали SFB Games наполняется Лором - персонажами, местами и событиями. Выглядит очень потенциально! Спасибо вам за прекрасную игру" Я обязательно куплю первую игру про Гриммуара чтобы поддержать разработчика.

I had a blast playing this game. The art style is so pretty, and there were so many unique, charming characters to meet. The 3D clues was really cool, the puzzles were diverse and fun, and the mystery was interesting. Very good game.
Best-in-class adventure game and an absolute must-play! Fun puzzles, excellent and well-written story, lovely animation, and top-tier voice acting performances.

Short and fun mystery! I had a blast playing this mystery game. Although there are some puzzles that are quite hard to grasp what you actually need to do (even with hints provided as non-native English speaker), I had fun playing this. It's like watching a real cartoon show, with controls and such. Would highly recommend if you're a mystery fan like me, or just wanted to try some chill, stress-free game on the side.
A great follow-up to Tangle Tower as the newest installment in the detective Grimoire series. Great atmosphere, decent puzzles and a mystery that's both gripping and enough twists to keep you wondering until the end.
