The Verge’s review finds The Mermaid Mask to be an engaging point-and-click murder mystery, built around the locked-room death of a submarine captain. Its confined submarine setting, colourful suspects and satisfying confrontations make it particularly effective as a compact, holiday-friendly detective game.

Players control returning detectives Grimoire and Sally as they question suspects, inspect detailed rooms and solve puzzles, with strong voice acting encouraging thorough exploration. The reviewer says newcomers need not have played Tangle Tower, and praises the roughly 10-hour game’s deduction sequences, though notes that repeatedly showing clues to suspects and following required evidence orders can become tedious.
