Launch Week Status
July 18, 2026 launch week update for The Mermaid Mask: no day-two patch yet, Steam Very Positive trend, walkthrough coverage limits, and wiki route expansions.
Two days after the July 16, 2026 worldwide release, The Mermaid Mask remains on its initial launch build across Steam, PlayStation 5, Nintendo Switch, and Nintendo Switch 2—no verified balance patch or hotfix has shipped as of July 18, 2026. Steam user reviews continue trending Very Positive with strong stability reports on PC and PS5, matching critic scores aggregated on our review roundup. SFB Games has not announced Switch 2 mouse-mode parity patches separately; use in-game and platform settings documented on controls hub if stereoscope puzzles feel imprecise on handheld hardware.
Walkthrough Coverage Boundaries
Public text walkthroughs verified through July 17–18 consistently end after the first full submarine crew sweep—Illusion Theatre, Child's Room, Dream Chamber, Cargo Hold, Engine Room, and Airlock Grotto introductions—without documenting finale reconstruction, killer accusation order, or a complete 21-achievement route. Our wiki mirrors that boundary: new guides for Dream Chamber and Airlock Grotto expand mid-deck coverage while we withhold unverified finale steps. Demo footage on YouTube (including early Steam Next Fest builds) covers prologue pacing only and should not be treated as full-game evidence.
