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...

This is an amazing improvement over Tangle Tower. This time they managed to explain the mystery in a satisfactory way that doesent seem rushed or just pulled out of their asses. I'll be wating for the next mystery of Grimoire and Sally!
Amazing game! it took 13 hours to finish, including reading about the project. definitely worth the money!!

The Mermaid Mask is the third instalment in the Detective Grimoire series, where you try to solve a murder on a submarine. This game is as funny and charming and, at times, terrifying as the previous games. The art style is fun, the voice acting is great, and the mystery and ending are both very solid.
All 3 games (to date) are all very good
Excellent game. The best parts are probably the writing and voice acting. It's very funny without trying too hard, and the characters are all likeable. A lot of the gameplay boils down to showing each person each piece of evidence, but the writing is so good that it never feels like a chore. The puzzles are good as well, ranging from "oh that was fun and clever" to "okay I know what the answer is, why is it not working." But if you like games akin to Phoenix Wright or Professor Layton, this is sure to be a great time for you. And without spoiling, this game's ending is much better than the previous game's. If a sequel ever happens I'd buy it in a heartbeat.
Spectacular game- an improvement of the first one in every way, which was a tall order considering how good the first one was. The voice work was always fun, the jokes always landed and oh my GOD the vibes! This game nails down its vibe an atmosphere and never once drops it. I had so much fun playing this game I think any fan of mystery, puzzle and point and click games will enjoy this one
F*ck yeah. Greatly exceeded my expectations, which were HIGH. I can't remember the last time I enjoyed a sequel this much more than the previous entries, even though I'm already super fond of them. Excellent on all accounts, both as a stand-alone mystery & weirdness story and as one more piece of the puzzle in this world. Chef kiss.
전작을 한지가 꽤 되었긴 하지만, 확실히 진일보했다는 인상을 받았습니다. 특히나 인상깊었던 부분이, 다른 추리게임에서는 연관성 있는 단서를 제시해도 원하는 단서를 제시하지 않으면 무조건 오답이라고만 하는데 나중에 사용하겠다, 내지는 관련이 있지만 생각과는 다르다 등 비록 정답은 정해져 있더라도, 플레이어하는 입장을 상당히 깊게 고심한 것 같다는 생각이 듭니다. 인물과 단서 제시하고 교환하는 어찌보면 사소할 수 있는 상호작용도 성의있게 구성하고 더빙까지 되어있습니다. 덕분에 타 게임 같았으면 의미없다 여겨지는 부분은 제시도 안하고 그냥 지나가는 경우가 많은데 대단히 영향력있는 문답이 아니더라도 제시하고 반응을 보는 것도 하나의 재미요소로 작용한 것 같습니다. 여러모로 플레이하는 입장을 깊게 고려했다는 생각을 주는 훌륭한 게임입니다. 추리요소나 스토리가 대단하다 까지는 아니지만, 기본에는 충분하고도 남고 추리나 탐문 탐색을 잘 못하는 분이라도 힌트를 사용하면 무리없이 진행가능할 것 같습니다.
There are no spoilers in this review. Short version: It's a bigger and better [i]Tangle Tower![/i] You examine clues, interrogate some fun characters, solve a few puzzles, and unearth people's secrets. The writing is great, and very funny in places. The quality of the animation and the voice acting is a joy to watch. And in some ways, watching is mostly what you're doing. I'd pieced some things together, and I wasn't at all unsatisfied, but there definitely were points where I was clicking the button to accuse someone of something, without knowing what that was going to be. The ending also, I really had no idea who was responsible for the murder. But I really enjoyed the ride anyway, and I'm happy that I did put enough together for it to be satisfying. Like [i]Tangle Tower[/i], there are a bunch of secret achievements that are easy to miss, and would require replaying the whole game again to get. I missed a couple despite being thorough. Also like TT, the game ends with some mysteries left unsolved. That's kinda the vibe though - this is a strange world with a lot of secrets, and connections between all the characters in the games so far. So I don't mind it. It's a little wonky in a couple of places if you play on an ultrawide monitor, but not badly.
Delightful.
