Whodunit Radio, officially titled 犯人当てラジオ in Japanese, now has a Steam store page. The latest game from indie developer 風切羽 is structured as an omnibus mystery novel game in which players read short cases and determine who committed the crime.
Six scenarios are planned, taking place across different times and locations. Instead of simply reaching the end of a story and selecting an answer, players can organize case information through cards and charts before committing to their deduction.

Steam, Key Art and Gameplay
Six Separate Mystery Cases
Whodunit Radio is not structured around one continuous case. Its Steam description states that the game contains six scenarios, each presenting a short mystery in a different time and place.
The omnibus format allows each scenario to function as its own deduction challenge rather than stretching a single case across the entire game.
Cards and Charts Support the Deduction Process
The central goal remains straightforward: read the case and identify the culprit.
Its distinctive element is the use of cards and charts to organize information. These tools are designed to help players see relationships between clues before choosing their conclusion.
From the Developer of Status Check Detective
風切羽 previously released Status Check Detective (ステータス確認探偵) on Steam in October 2025.
That game also centered on solving mysteries, but used character statistics as its main investigative gimmick. Whodunit Radio takes a different direction through multiple short cases and its card-and-chart deduction format.
Still Scheduled for 2026
The Steam page is now live and includes an official PV, but a specific launch date has not been posted.
With the release window still listed as 2026, the next major details to watch are its exact date, pricing and further information about the six scenarios.
Why This Matters
1) Six cases provide a naturally segmented structure
Each mystery can introduce a different culprit, setting and clue set without requiring one oversized central case.
2) Deduction is visualized through cards and charts
Case information is not limited to passive reading and can instead be organized as part of the reasoning process.
3) The developer is returning to mystery games
Following Status Check Detective, 風切羽 is once again building a game around the process of finding an answer.
