Release Date Announcement

We’re thrilled to announce that The Mermaid Mask launches on Steam on July 16, 2026.

All aboard the world’s strangest submarine

Summoned by the mysterious Captain Seafoam, Detective Grimoire and Sally arrive with only a cryptic letter, two photographs, and the growing sense that all is not right aboard the Mortuga Submarine.

You’ll explore a hand-crafted submarine, interrogate a fully voiced cast of oddballs, gather evidence, solve puzzles, and slowly assemble the murky truth lying beneath all the surface.

Expect:

• An impossible locked-room murder

• A strange submarine full of secrets

• Eccentric suspects with plenty to say

• Clues, contradictions, and satisfying “aha!” moments

• Cozy-creepy mystery vibes

• Sally being extra Sally
