The Mermaid Mask Review: Grimoire's Greatest Adventure

The murder mystery genre often adheres to a rigid formula, but The Mermaid Mask, the latest installment in the Detective Grimoire series, masterfully navigates these conventions to deliver an exceptional narrative experience. SFB Games has crafted a title that embraces the genre's tropes while simultaneously offering exciting and memorable storytelling, complemented by eye-catching animations and a spirited voice cast. The game's success lies not only in its plot but also in the engaging way it's presented.

The investigation centers on the murder of Captain Magnus Mortuga aboard his submarine, the Mortuga. Players step into the shoes of Detective Grimoire and his assistant Sally as they unravel the mystery. The ensuing investigation is compelling, culminating in a surprising and satisfying conclusion that surpasses the final moments of the studio's previous title, Tangle Tower. The art and animation accompanying the investigation's climax are particularly noteworthy, standing out as highlights of the game. SFB Games also excels at writing witty and naturalistic character dialogue, brought to life by the strong line deliveries of Grimoire and Sally.

The Mermaid Mask unfolds entirely within the confines of the submarine, blending point-and-click mechanics with puzzle-solving and extensive conversations with the vessel's eclectic inhabitants. Each room is uniquely designed, reflecting its occupant and featuring approximately 50 pieces of evidence scattered throughout for players to examine. While the sheer volume of clues can become overwhelming, especially when searching for the final pieces of information to advance the narrative, an optional and free hint system is available to assist players who feel stuck.

Dialogue is a significant component of The Mermaid Mask, yet every voice performance is engaging. Characters like Symmetry, with their near-Shakespearean cadence, Zephyr, whose deep voice imbues a sense of mystery, and Sinthia, with her endearing earnestness, all contribute to a cast that feels alive. This is further enhanced by charming character designs and detailed animation, which breathe life into the Mortuga's crew from the outset. An extensive art gallery, accessible after completion, showcases early concept art for each character, complete with artist commentary, offering a deeper look into the game's development.

The orchestral soundtrack, composed by Raphael Benjamin Meyer, effectively sets the tone without overpowering the dialogue and story. It is exciting enough to capture attention and specific enough for each situation, yet subtle enough to allow players to remain immersed in the character interactions. The game features a surprisingly large number of unique tracks, with distinct themes for each character and various minigames, a level of detail that elevates the overall experience.

Players are made to actively earn their discoveries in The Mermaid Mask. Beyond presenting the correct evidence, a staple fill-in-the-blank minigame requires players to draw conclusions from the gathered information. The game also incorporates numerous 3D puzzles, often used to unlock compartments or containers. These puzzles are inventive, featuring unique challenges such as manipulating facial expressions to form numbers, arranging skull grids, or cataloging mushroom species. While often appearing complex, most puzzles can be solved through careful observation, fostering a detective-like mindset. Grimoire and Sally offer additional details on failed attempts, providing assistance when needed.

Overall, The Mermaid Mask stands as the best Detective Grimoire adventure to date. Its art, music, voice acting, and puzzle design are all commendable, but they are anchored by a strong story and an engaging script filled with the wit and twists expected from SFB Games' mystery series. The game provides a consistently engrossing and engaging experience, leaving players hopeful for future installments.
