Does anyone know where online I could play this game on full screen?

Hello,

While it's not yet fullscreen, however, it is the highest resolution that you can find online for this game:

There is also an ongoing project for adding the fullscreen option as well. I can let you know once it is added.

Thanks @NuMuKi and i'm not doing dancing videos anymore @FreyaBBY
