Q. Why did she become a hikikomori?
Q. How does anonymous online posting lead to world destruction?
Q. Does a happy ending exist for a degenerate otaku?
The answers to those “Q” s lie at the convergence of insanity and denpa psychosis.
Now, put those headphones on and become ill with Yunyun Syndrome!? Rhythm Psychosis.
Get high on denpa songs and spread your heartful psychosis to everyone else!
・Qtie (CV:Nanahira)
The main character. A hikikomori. She suffered too much irl that she’s become a little (very) fuzzy in the head. Her obsessive love for the fictional character “Yunyun” is for sure an illness. Her overly “high” state from overdosing denpa songs causes her to propagate Yunyun love. Will there really be a happy end for such a degenerate otaku?
・Yunyun (CV:Haruko Momoi)
A fictional character that loves Qtie. A very much angelic devil. She will speak to Qtie through the monitor screen. Whilst the truth is unknown, most likely, she is just a figment of Qtie's imagination. It’s joever for her.
Q. What is a “denpa” song?
It is a genre of music that is intentionally strange and catchy. All playable songs in this game are denpa songs.
Many popular denpa songs such as “it’s a cherry kissing explosion” (Sakuranbo Kiss) and many more are featured!

Strange translation occasionally, but the ♥♥♥♥♥♥♥♥ theories are 'well written' for jokes. Really addictive gameplay and good rhythm game maps, just wish there was more on there that isn't locked behind paid DLC. Rim de lacent <3

Rim de lacent!

心目中独一档的神作 很久没有这么对上电波的作品了
아트웍만 보고 게임을 골라선 안된다는 걸 다시 한번 깨우쳐주게 한 게임. dlc 없이는 음악이 너무 적다 보니 어느 순간 같은 곡만 n번째 반복하게 됨. 다른 리듬게임이랑 비교해 봤을 때도 어디선가 다 보던 느낌이고 이 게임만의 특별함이라곤 음악이 대부분 전파송이라는거. 그래서 스토리가 훌륭한가? 라고 하기엔 솔직히 스토리도 그렇게 좋지가 않았다. 스토리, 게임성 두개가 ㅈ박았는데 뭘 보고 이 게임을 해야 하나 싶다. 우리는 게임을 하고 싶은거지 아트워크 감상이 목적이 아닌데 말이지
好玩啊好玩!!!!!!!!
залипла, теперь хочется включать как минимум чтобы посмотреть на приятную картинку и послушать музыку на фоне
シナリオ、優しい設計の音ゲー、インターネットに浸かっていればいるほど笑える小ネタ。最高のゲーム体験でした。これから全曲フルコンボ挑戦してきます。
Yunyun Syndrome is a unique rhythm game where you are observing a shut-in's delusional love of a fictional character. There are many interactive scenes involved where you experience multiple funny and few important outcomes that can reveal more about Qtie's backstory, the main character. If you are a fan of rhythm games and don't mind some dark themes, I would recommend this one.
