About the Game

Garisani Detective Agency is a real-time two-player co-op deduction game.

One plays as a human, gathering clues through conversation and on-site investigation. The other plays as a ghost, using whispers instead of words and exploring hidden spaces. Together, you piece together different clues to uncover the truth.

Four stages await, each a case with its own structure. They don't just get harder—every stage brings new characters and puzzles for a fresh experience.

Communication

The defining feature is information asymmetry: the two players collect different evidence, and each must work through their own role. Co-op mode is built around this and does not support voice chat.

Co-op Deduction

Two partners, one goal: solve the case. Work it out through relentless communication! Place your evidence on the case board to share what you've each found, and experience a one-of-a-kind deduction mechanic.
