Set in 1990s Korea, the game follows a brother and his ghost sister as they run a detective agency and take cases from both the living and the dead.
Two players investigate from different roles: the human gathers information through conversations and on-site searches, while the ghost uses whispers and can explore hidden spaces. Each finds evidence the other does not, so partners need to communicate what they learn.
The pair bring their findings together on a case board, pinning clues to support deductions and solving puzzles along the way. The story spans four cases, with new characters and puzzles in each; reviews also mention arcade minigames in a game-room location.
Players who enjoy the game often value its unusual human-and-ghost teamwork, the fun of comparing evidence with a partner, and a story that connects the cases. Some also praise the character designs and lighthearted tone. Others say the central clue-linking system can be frustratingly exact: they may understand a case but struggle to identify the specific evidence pairing the game accepts.
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.
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.
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.
