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...

9.5/10 The story was Gripping, it felt like it had something to say more than just "someone died." It follows up Tangle Tower with a much more satisfying cast, more to investigate, and a greater sense of mystery for who the killer might be. The previous game had an ass-pull for its killer but this game's ending was incredibly satisfying. My only problem with this game was that some of the puzzles, very few of them, had unintuitive goals, unintuitive mechanics, and unintuitive connections to the actual game world. Some of the puzzles felt like video game levels instead of physical locks on objects in a world, and you had to get a hint by failing a few times to even figure out what you were supposed to do with the pieces. The puzzles aren't the point of the game anyway, and only like 4% had this issue, so I would heavily recommend this game.

WOW! This game was soooo GOOD! The Grimoire games keep getting better and better with every new game. A lot of the things I liked less about Tangle Tower got improved in this one: A more believable story of the murder and better reasoning of the culprit, a more elaborate ending + a brief look to the future of the remaining characters (after the events) + the time it takes to finish the game went up quite a lot (basically doubled) which was fun! I'm very happy the developers went in a slightly different direction with the story this time as the last two games both had the 'searching for mystids/cryptids' storyline which felt a little too similiar. This time they went with an object rather than an animal/creature as the main thing, which felt refreshing! The artstyle, location- and character design were truly GORGEOUS, as to be expected from this incredible team! + The voice acting was so GOOD as well, they truly made the characters come to life! This game and its story felt the most complete and real out of all the Grimoire games so far! I also prefer how this game had very subtle mentions of characters from the earlier games, the ending was so sweet as well! As mentioned earlier the Secrets of the swamp and Tangle tower were a LOT of FUN, but they did feel a little too similiar. This game felt very refreshing! I also really liked the new characters and prefer the characters not all having the same 3 last names haha (Fellow etc.). My only complaint would be that the talking to the characters went on a little too long at times. Asking them about all the suspects, clues and asking the questions was fun, but seemed to take just a bit too long as I felt my attention slither away every now and then and found myself clicking through some of the dialogue to get through everything. I prefer puzzles and looking around the locations for clues over dialogue, so this felt just a bit unbalanced. It would have been even more fun with a few extra clues or puzzles and a little less lenghty dialogue parts here and there. Still I am incredibly excited to see more!!! I'll be patiently waiting for the next game, whatever it may be!
It was a long wait, but the game was worth it. I played the previous installments with my 10yo kid and he insisted on putting The Mermaid Mask on the wishlist. So we did, and regularly checked on the release date. At last we had a free weekend together, and cracked the game (3 achievements missing...) in 16 hours. The story was really great, everything logically connected, every character with unique quirks and traits. There was a stage where we had to ask everyone about everything, because sometimes the comments pushing the story forward were a bit unexpected. But once all clues were unlocked, in the endgame, all started to fall into place in the most satisfying and logical way, leaving no loose ends. Really wholesome and touching experience, for something disguised as a "detective game". My kid already asks about the next part!
非常好玩的轻度解密游戏,画风美丽,难度适中,比前作内容量更大,小游戏也有意思,推荐。
10/10 game, one of the best indie games ive ever played
Amazing. Worth all the wait. Small aside the achievement for finishing the game didn't trigger on my playthrough.
I played the previous game with these characters, so I already knew I was going to love this one. I had pretty high expectations for The Mermaid Mask, and somehow it absolutely lived up to them!!! The characters are still one of my favorite parts. I loved seeing Grimoire and Sally again, the dialogue is genuinely funny, and the new characters fit into the whole weird little world perfectly. The mystery kept me hooked the entire time. I kept coming up with theories, changing my mind, suspecting someone else, and then changing my mind AGAIN. Exactly what I want from a detective game! The puzzles, the art, the voice acting, the humor, the atmosphere... everything just works. I honestly didn’t want it to end. Please give me another Grimoire and Sally mystery!!! I’m not done with these two yet!!!
One of the best Detective stories I've experienced.
I loved Tangled Tower, and I LOVED the mermaid mask! Its truly a testament to what this studio can do! BUY IT AND PLAY IT!!!!!!!
Another great installment. Great story and voice acting. The art gallery is a treasure trove.
