About the Demo
This special demo features roughly 30 minutes of gameplay from the early portion of Yunyun Syndrome!? Rhythm Psychosis, including both the rhythm and adventure segments of the full game loop.
While the story does not progress beyond the demo range, you can continue playing after completing the main section.
The full release will feature full Japanese voice acting for Qtie (VA: Nanahira) and Yunyun (VA: Haruko Momoi). Please note that some voice lines are not included in the demo version.
Players can also enjoy around 10 denpa songs, including hidden tracks, during the demo period. The limited-time demo will be available from October 10 through October 31, 2025.
Start your denpa descent today and feel the “Yunyun Syndrome” for yourself!
