What people are saying
Updated nightlyMost people digging this rhythm game say the core hook is great, with the denpa soundtrack and Yunyun's character being the real standouts. It's a very niche vibe about internet brain rot that lands perfectly for its target audience, and the art style gets consistent praise. The main complaints are all technical: the PC port's performance is spotty, and people are pretty fed up with the developer, WSS playground, over how it runs. It's a fun, weird ride if you're into this specific aesthetic, just expect some jank.
