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...

才玩了半个小时我已经被这个游戏的玩法创意和美术惊艳到了 10/10
If you are new to detective games, I would highly recommend this game. The graphics, story, and voice acting have a high amount of detail and love put into them. The game isn't as punishing if you get something wrong when connecting evidence and solving the case, and it even gives hints on what to do if you are stuck on certain parts of the game. The only downsides are that it may be a pain to find certain evidence in a location since it is a point-and-click game where some items may be misleading, and the majority of the puzzles are easy to know what to do and solve. Otherwise, amazing game, would play again.

ITS SO ♥♥♥♥♥♥ GOOD
Better than the last one. Please keep updating the series and keep up the good work.
11/10 This one has a kitchen.
好玩!都来玩!打完前作来玩这作非常享受啊,全方位升级之!希梅希梅妈妈的好宝宝,妈妈爱你❤ 结局演出我非常喜欢!很难用语言形容!这一作的杀人动机和手法都非常明确有趣(前作在这里确实有点潦草了),好玩好玩制作组别休息了快出下一作
I'm nit-picky as hell. Very high standards. And yet, this is basically the perfect mystery game. It's got everything: an incredible voice cast, gorgeous art and animations, a musical score that puts Hollywood heavy-hitters to shame, tight writing, a satisfying and unsettling reveal at the end, and character writing that somehow had me falling in love with every single character. The first game stumbled a little on scope and some of the voice lines (audio quality, mostly). The second game was amazing but failed to stick the landing on the ending. This game took everything the studio learned from the first two and made something absolutely perfect. If you're on the fence about this series, drop what you're doing and get all three. The character writing and worldbuilding never waver in quality, and they all build off each other in a way that improves each entry in the series. They're relatively short and 100% worth your time and money. I'm crossing my fingers and praying the studio doesn't make this the last entry. Whatever they put out next, I'm buying on launch day with no hesitation.
发现续作上了就购入了,和上作一样的美术风格太对味儿了(可惜有些场景的小人被换成3d版的了也有种抽象的可爱吧)但是Sally可爱捏 结局依旧谜语人[spoiler](打完变得和气球小哥一样也很想知道人鱼说了什么)[/spoiler]结局动画还是挺震撼的,比之前收尾好一点吧! 还有就是这个打完了又不能回去补成就了,漏了成就得重新开档好痛苦TT 最后是有点没玩够 请为了玩家使用出续作的力量吧!
Detective Grimoire series is always entertaining and hook me from start to end. The amount of content is just about right the puzzles are fun and not too hard. Everything is just right with this game.
Loved every minute of The Mermaid Mask! This tiny murder sub is chock full of brilliant characters, gorgeous art, and perhaps the best dialogue and vocal performances I’ve heard all year. But it’s the central mystery at the heart of it all that really makes it special. Clicking along, watching the clues come together, smacking my forehead as the little bits I thought were throwaway red herrings fell into place to create an extraordinary finale, was such a satisfying treat. I can’t recommend The Mermaid Mask enough. Here’s hoping Grimoire and Sally will be back on another case in the near-ish future.
