What is this class design of Dancer?

[Gihwezi]

Also, Dancer doesn't penalize you for mistakes when dancing the same way ninja does with messed up mudras. If you hit the wrong button you just lose 1 second of uptime and then need to be sure to hit the correct one next.

Yeah, the first time I missed a step I just assumed I was gonna eat a huge ninja-esque penalty and just stood there waiting for it, assuming I'd never be able to finish the dance, but was super surprised that I could keep going without being punished! It's a really, really forgiving job, it's great!
