How it feels
A chaotic, denpa-fueled rhythm adventure where you lose control to spread internet brain rot.

What players say
Players praise the music, art, and unhinged storytelling, but the English translation is widely condemned for inserting Zoomer slang, with many recommending fan patches. The game is a 4-key rhythm game with a thin song list and DLC complaints, though its denpa aesthetic and character appeal create a cult following.
