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...

Jogo incrivel como sequencia do Tangle Tower, mts surpresas até o final do jogo. Vale cada centavo.
It's good :)
First off - make sure you play Tangle Tower first!! There are several references that, while not critical to the story of Mermaid Mask, definitely make a lot more sense if you've played Tangle Tower first. The highlights of this game are definitely the superb voice acting and the VERY well done script.

After the brilliance of Tangle Tower I've been waiting for this game with so much anticipation and excitement that there was a real risk it couldn't possibly live up to my expectations. But it did and more! Beautiful, funny, original art style, brilliant characters, clever puzzles, and a perfect storyline. I highly recommend!
Great game, lovely artstyle and interesting story, a great game after tangle tower
AMAZING! Buy as SOON as possible!
Great. If you liked the first 2 Games you will love this one. Pretty much everything got a big upgrade and the charm is still here. I also don't want to spoil anything, but in my opinion this is the best story this franchise had so far by far.
INCREDIBLE GAME!!! I already loved Tangle Tower, so I knew it was going to be good, but no THIS good! The animations and voice acting is unbelievable, the music is magical and the mystery, the story is so refreshing! I wish I could experience it for the first time again. What. An. Experience.
Charming, fun, witty, and extremely well executed! This is a worthy successor to their first adventure and a very welcome installment to what I hope is a long and successful franchise.
Another solid entry in this point-and-click detective series! Loved the entire thing! Some pretty tricky puzzles, plenty of solid voice work with a funny script, interesting characters, and basically twice as long as the previous game if you take your time! A solid step up from Tangle Tower, which was already a great game on its own! Namely, now EVERY suspect has something to say about EVERY clue, rather than having a generic "I don't know" line for clues that are not linked to them. Adds way more depth to the characters! Absolutely no complaints beyond the long wait time for the game's eventual release, but I do feel it was worth it! Definitely pick it up if you love the series or just detective games in general!
