    We absolutely loved this! Not only were both parts so unexpected... we enjoyed accusing each other over the smallest things! The interactive form was such a brilliant take and we recommend this so much!

Mature Content Warning 18+ - Psychological disorders and disturbing themes

6.5 Hour Epic Runtime - Extended gameplay with multiple story phases

6 characters players + 1 host - Host is mandatory

Open-Book Collaborative Deduction - All information shareable between players

Six diaries washed back with the tide. One name no one wants to say. Read, share, and piece together the truth before the island takes it back.

The sea took the town once. The people came back anyway.

On a winter week when the tide runs high, six letters surface and the mansion doors open. Rooms look tidy. Stories don’t. Somewhere between a cenotaph and a sewing table, someone crossed a line they can’t uncross.

Dive into the twisted minds of six disturbed individuals as they uncover the truth behind a mysterious "no survivors" incident on the remote Cat Island. Murder on Cat Island is an intensely story-driven murder mystery game that challenges players to reconstruct not just how the murders happened, but why—through multiple layers of truth that will leave everyone questioning what they thought they knew.

Unlike traditional murder mysteries, this game focuses 70% on story reconstruction and character psychology, with 30% deduction puzzles. Players must think like their morally twisted characters rather than applying real-world logic, creating a uniquely immersive psychological experience.

Each player holds a diary from Cat Island’s past. Read in private, then speak what your writer left behind. Secrets knot. Alibis slip. The tide won’t wait.

You’ll probe ledgers, follow a ferryman’s note, test what a “witness” really saw, and decide who’s telling the truth when the island refuses to help. By the end, one person names the killer—and everyone hears what it cost.

Key Features

  • Multi-layered narrative: Discover three completely different versions of the truth, each equally plausible
  • Open-book deduction: All information is shareable—success depends on collaborative reasoning
  • Psychological depth: Explore the disturbed minds of characters with extreme personality disorders
  • Role-based reasoning: Players must embrace their character's twisted psychology
  • Epic runtime: 6.5 hours of intense story reconstruction and deduction
  • Complete story arc: Multiple dramatic reveals and emotional payoffs

Why This Game Stands Out

Triple Truth Mystery

One Crime, Three Completely Different Killers: Unlike traditional mysteries with one solution, Murder on Cat Island presents three equally valid versions of the truth. Each reconstruction reveals a different killer with completely different motives, forcing players to question the very nature of truth itself. No other murder mystery game delivers this level of narrative complexity.

Psychological Character Immersion

Play as the Villain, Think Like the Disturbed: Players don't solve crimes—they become psychologically twisted characters with extreme personality disorders. Success requires abandoning normal moral reasoning and fully embracing each character's disturbed worldview. This creates an intensely immersive experience where players must think like cannibals, necrophiliacs, and obsessive stalkers.

Story-First Deduction

 70% Narrative, 30% Logic Puzzles: While most mystery games focus on "whodunit," Murder on Cat Island asks "why did they do it" across multiple timeline reconstructions. Players spend hours unraveling character motivations, family histories, and psychological trauma that led to mass murder. The deduction serves the story, not the other way around.
