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!

Конец Евангелиона, но если бы Синдзи был девочкой-шизопостером с тульпой.
одна из лучших моих игр, сюжет афигенный, для не любителей ритма есть авторежим и кучу мелких концовок. осталось последнее достижение и будет окончательно 100%

Game is excellent for anyone who likes Rhythm games. But you HAVE to like the nerdy aspects of japanese culture. I think that an unfamiliar person will not understand the story (I barely understand it). I do think there's some room for quality of life improvements that other rhythm games have. Using more screen for the game area (full screen height), and color coding notes to different beats (which is a standard option in a lot of rhythm games). As is the left and right notes are one color, center notes are the other, which tells the player basically nothing. The typing area is a fun detail, but could easily be pushed to the side rather than taking up the bottom 1/3rd of the screen. Still good, and recommended.
so peak.... reminds me a lot of NSO but as a rhythm game
very cool I love this game but I sadly barely played cause as of writing this theres a bug that causes the game to not register random key presses on linux :(
SUPER FUNNNNNNNNNNNNNN
I Love you Yunyun.

[h1]#The Screaming beaver is an Agarthan and plans to take over the surface [/h1] Really cool and sweet rythm game about a schizofrenic hikkomori spreading s.hitposts on the internet, with some great soundtrack, and a low skill floor allowing noobs like me to play and enjoy it, and a decent skill cealing that i haven't reached obviously. The game has a pretty good story and well likable characters, and its humour landed pretty well for me. The game isn't super deep with its mechanics or long with its playtime, but for the really low price tag, you can't really get mad at it, especially when it makes up for that with the ammount of soul it has. [h2] Overall 8/10 i really recomend it to people like me who suck at rythm games but still want to enjoy them and improve gradually, and also for fans of modern Japanese culture (Touhou :) ) [/h2] [i] PS. all the reviews coping about the translation are out of date, it has been improved significantly since launch.
