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...

Großartige Spielereihe Die Dectective Grimoire Reihe macht alles richtig, was ich sonst nicht an Point & Click Adventure mag. Ich liebe vor allem die Charaktere und die Geschichte, und da macht "The Mermaid Mask" keine Ausnahme. Es ist das bisher längste Spiel der Reihe und ich hab auch schon wie bei den anderen Titeln jede Sekunde genossen. Ich hatte das Gefühl, dass die Rätsel bisher die schwersten der Reihe waren, aber sie waren immer schlüssig. Auch wenn es eine Spielreihe ist, steht jeder Teil für sich und es ist nicht notwendig, die Vorgänger zu spielen. Es ist auch schon eine Weile her, dass ich die vergangenen Teile gespielt habe. Deshalb habe ich manche Verbindungen nicht erkannt, es wird also mal wieder Zeit.
Honestly a great mystery game for the price. You can tell both Tangle Tower and this has so much work put in. Characters, animation, story and music are superb. Puzzles are great. Really want more from this series.

This was a really fun yet challenging mystery! All of the characters were charming in personality, history, and especially in their design. I do appreciate the optional hints as well, as sometimes that small point in the right direction is what I need from a game like this.
LOVE the quality, story and animations it looks SO nice and i love it,
NB B NG 캐릭터들의 특징들이 다 좋았어요
an all timer point and click franchise. the humor is on point without being juvenile or too smug with itself. the voice acting is top tier. the character design and animation feel nostalgic and beautiful. most importantly, this game somehow avoids the pitfall of 99% of point and clicks where you make fast progress at first and then suddenly stall out and waste hours revisiting the same rooms and objects with no clear sense of how to advance the game. Mermaid Mask achieves the near-impossible and keeps the momentum the entire time. i felt like i was always making new delightful discoveries and hurtling full throttle to the big reveal. 10/10 🧜♀️
The presentation for the mystery and untangling the suspicions is so much more ambitious and I think it largely pays off. Stellar voice cast once again. Some minor qualms about the mystery setup but those barely matter. Introducing 3D for some puzzles helps with variety and the space within which you have to think. All in all, a very fun game with a great cast of characters to spend time with and pick apart the lies to get at the truth.
What a delightful game! I was so excited when I saw the announcement for this game and even replayed the other two Grimoire games in anticipation for this one and man, it did not disappoint. The voice-acting and dialogues were phenomenal of course and the art style was as captivating as ever! This game can be played as a standalone, but I do recommend playing the first two games, just for the hints/references that brought a smile to my face every time :) I had an absolutely lovely time playing it <3
Fantastic game, had a great time with the artwork and the story and reading through the art gallery. The ways The Mermaid Mask related back to Tangle Tower was fascinating and made me want to replay the game. Excited for the next one! There's still some hidden lore about part of the story that I wish would be unveiled in the future.
Mais um jogo maravilhoso do detetive Grimoire e da Sally! Mermaid Mask tem um enredo bem intrigante, personagens carismáticos pra questionar, uma arte muito bonita com animações divertidas, vozes muito boas e tem também uma tradução pt-br oficial muito boa! Revomendadissimo! Pra quem gosta de achievements, cuidado: tem três que são fáceis de perder.
