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...

I read so quickly that unskippable dialogue fills me with rage. The voice acting in this game - no, this series - is so good I didn't want to skip anything. Can't wait for the next one!
Good little puzzle adventure
Another great Detective Grimoire game! Great art style, great voice acting and great music! If you liked the previous ones, you'll enjoy this one too. The 3d interactive clues make it even more interesting, but also slightly harder, since now what you're looking for could be hidden inside. That also comes with one issue I encountered - there is at least one "proof" that can be reached through two different "clues", but the game will only accept one of those paths, even though both lead to the exact same "proof". This got me confused quite a bit.

Everything that was amazing about Tangle Tower has been transferred over to Mermaid Mask and improved upon 10 fold! A++ game! Loved every minute! Gathering the clues and listening to the characters to puzzle out the murder was very satisfying. I think there were about two puzzles that I got super stumped on, but nothing to make me incredibly frustrated. Just sometimes wished they would let me know what piece I had right. Otherwise, A beautiful and fun murder mystery. I am making my friends play this >:)
Same formula with new characters, that are even more fun to interact with and uncover their secrets. Main case hooks right away and the soundtrack is a vibe. Really good sequel, hope there will be more installments in the future.
After falling in love with Tangle Tower, I couldn’t wait to dive into The Mermaid Mask, and it absolutely did not disappoint. While I personally enjoyed the mystery in Tangle Tower a little more, the developers once again delivered an incredibly engaging detective experience. Every conversation and every clue had my brain working overtime as I tried to piece together who the killer was. I suspected from early on that it had to be someone unexpected… and to my delight, I actually figured it out before the big reveal. 😂 That made the ending even more satisfying. The writing, characters, and puzzles kept me invested from start to finish. Overall, I highly recommend The Mermaid Mask, especially if you enjoyed Tangle Tower or love mystery games that let you play detective. It was an absolute blast from beginning to end, and playing it on the Steam Deck made the experience even better.
还是《tangle tower》的那个味儿,但是把上一作槽点最大的结尾也做的非常优秀了,这次是真的没有什么缺点了,神作!(但推理成分还是比较轻,基本上就是到处点然后把找到的证物给所有人都看一遍就过了,推理环节因为没有失败惩罚,感觉也很简单,我感觉当成悬疑推理小说玩会更合适) 另外,我真的很喜欢侦探二人组的人设啊,特别是莎莉,不仅很风趣,而且配音真的很涩(好喜欢这种欧美风大姐姐😍)
탱글타워도 재밌게 했는데 인어가면이 훨씬 잘 만들었네요 전작도 그랬지만 성우연기가 너무 좋아서 스킵 안하고 여러번 들었습니다 후속작 제발 나왔으면 좋겠어요 캐디랑 아트 취저라서 더 보고싶어요 아 그리고 제작사 다른겜 크로우컨트리도 ㄹㅇ잘만들었음
apaixonado meu deus queremos o proximo
A good sequel to Tangle Tower.
