My rhythm game PadManiacs on autoplay! This is a web-based StepMania clone I’ve been developing that you can play right in your browser, on Windows, or Android.

The song is “Cirno’s Perfect Math Class” from Touhou Project (from the godai simfiles pack). The game plays itself here to show off the mechanics and visuals.
