Evaluation

Garisani Detective Agency officially launched on July 14, 2026, developed by a four-person student team in Korea. The game shipped with four story stages as its complete base content. In the pre-launch post on July 13, 2026, the developer described what the official release would include — an improved investigation board, a reworked Stage 1, and full story content for Stages 2, 3, and 4 becoming playable for the first time. Since launch, the team has issued several bug fix patches (July 16 and July 22, 2026, and August 4, 2026) addressing translation errors, puzzle bugs, spawn issues, and other polish items. On September 9, 2026, the developer announced participation in the GXG 2026 x INDIECRAFT expo on September 11–12, 2026, where they showcased an exclusive EX Stage and a solo mode available only at the event booth. This indicates the team is still actively engaged with the game, but the expo content was not announced as a general release for all players. The developer has not communicated any plans for additional stages, DLC, or ongoing content beyond the base game for the general playerbase. Given the game launched on July 14, 2026, it is still early enough that the developer's long-term content intentions remain unclear.

Evidence

Pre-launch post confirms the official release includes Stages 2–4 for the first time, with the game developed by four university students in under a year. Developer notes ongoing localization refinements and plans to respond to feedback.

About this 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.
