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...

Soooooo... When's the next one? :3
Mermaid Mask is puzzle-solving-meets-detective-em-up at its finest. Every aspect is polished to an absolute mirror sheen. The dev's previous adventure Tangle Tower was an almost-quite-there puzzler that banked on its excellent visuals and engaging dialogue to keep folks going through some occasionally difficult-to-follow plot; Mermaid Mask has no such reservations about its recommendation. The characters are universally engaging - both in terms of their animation and their personalities. Stock archetypes - the fez-wearing occultist, the wacky aeronaut, the supernaturally inclined orphan - are polished, faceted, and given this really loving depth in almost every animation, line read, and tangential aside. I particularly love how certain characters' animations will cut mid-sentence due to the inflection placed on a certain line - just to add a little bit of oomph, to make their reactions feel just that more human. Other VNs I've played have not had as much care placed into their whole cast as one Mermaid Mask character gets in his whole animation set. The story is compelling from a high-level view and at the line-by-line level; well-paced, witty without being overly quirky, occasionally quite emotional. Our main duo are quippers about the strange circumstances they find themselves on, but you're never led to believe they don't care. The writing is so good that even when characters simply pause, you truly have many things to consider is it a muted concern, a held, self-aggrandizing breath, silent reproach? Each suspect has reasons to have committed the crime - some understandable, some less so - but the great achievement the game's writing makes is that by the end I really didn't want to pull the mask off the culprit, because doing so would untangle the ravel of strange affections this cast held for each other. I could go on at length about everything else, but one particular standout was the music. I've been listening to J.D.'s theme off and on for days, it's that good. Holy cow.

This thrilling tale of thoughtful twists, A story stitched by silken strands, What lofty legends linger yet! The tale as told is best traversed through twisting trails of treason. Regard revenge a rueful road, Else torment trample reason... (10/10)
This is a fantastic follow-up to Tangle Tower, which I'm really glad I replayed right before this. The gameplay is super smooth and the story super compelling. I feel like just about anyone would enjoy this, although they should play the previous game first. I really like the way the larger story is unfolding from game to game. Can't wait for the next one!
I thoroughly enjoyed the previous two games in this series and had a lot of fun playing this game as well. The first twenty minutes or so was a little confusing as you get used to everything, but after you get a feel for the layout and characters, it's easy to get sucked in. The game play itself was very smooth, the story telling had great depth, and the pacing of the reveal felt much less rushed than the previous game in the series. Leaves the player with some unanswered questions, but not necessarily in a bad way.
Absolutely incredible. Just as good as the first one.
굿
Fantasic game as expected after Tangle Tower. Definitely was worth the wait.
The graphics are cute but the story and gameplay feel lacking for the price. 12h gameplay and pretty simple puzzles are not enough for me
