Yunyun Syndrome!? Rhythm Psychosis, the insane rhythm adventure from publisher Alliance Arts and developer WHO YOU, uploads deranged slop posts on PC via Steam today at 9:00 PM PT for $16.99 with a limited-time 10% launch discount until Friday, May 8, 2026.
Tap to the music and move to the beat, as the social recluse Qtie. Escape annoying human interactions and dive into the digital realm. Type out endless degenerate posts to express Qtie’s excessive devotion for the adorable online persona Yunyun, and drown out the Yunyun haters with downvotes on their negative comments!
Who is Yunyun?? Well, she could be an angelic devil sent to save poor souls from a world full of nonsense, or perhaps she’s merely a fictional character that only exists in Qtie’s imagination… Anyyyyyway, throw those headphones on and tap to the sounds of over 30 energetic tracks to praise Yunyun’s divine cuteness!
No one can stop this chaotic mess, even Qtie herself… or could she? Embrace chaos to reach a complete mental breakdown and become Yunyun-obsessed! Can’t wait to witness Yunyun’s unhinged charm? Focus on the rhythm of a psychotic shut-in’s online adventure, and collect multiple endings to uncover Qtie’s true finale and her sweet sweet love for Yunyun!
Type to the tempo of 5 additional song pack DLCs available for purchase at launch. Clack along to the game’s official soundtrack, featuring arrangements by popular denpa pop musicians. Customize Qtie’s keyboard with in-game skins to match the madness in her heart.
Yunyun Syndrome!? Rhythm Psychosis will be available on Steam later today at 9 PM PT. You can play the demo right now.
