What people are saying
Updated nightlyPeople mostly love this rhythm adventure about a psychotic hikikomori corrupting the world with brain rot, praising the unique story and the addictive rhythm gameplay that makes it easy to get hooked. The presentation is a huge hit, with the vibrant graphics and the denpa song soundtrack getting constant praise, and the main character Yunyun is a clear fan favorite. The main downside is technical, as performance issues like crashes and bugs come up regularly, especially on PC platforms like Steam, and the developer WSS playground is frequently criticized for these problems. It's a solid package for the price if you're into the very specific vibe, but be ready for some jank.
