“Yunyun Syndrome!? Rhythm Psychosis” is a rhythm adventure game about a psychotic hikikomori girl - also an avid anonymous poster - who corrupts the world with her severe brain rot from listening to too many denpa songs. Yunyun all over this world with your degen otaku-posting.
Most people found this rhythm adventure about a psychotic, brain-rotted hikikomori to be a weirdly compelling experience, with strong gameplay and a fittingly chaotic story. The real sticking point is its developer, WSS playground, who folks are overwhelmingly unhappy with due to issues around Steam, PC, and Twitch integration. While the core concept, Yunyun herself, and the denpa songs land well, the game's performance is notably rough and its value is questionable, making it a niche pick for those who vibe with its specific, unhinged energy.
