From the Dance Dance Immolation site:
Dance Dance Immolation is an adaptation of the popular arcade video game Dance Dance Revolution, but with fire! Basically, you play DDR; when you do well, the computer shoots big propane blasts up into the air. When you do poorly, it shoots you in the face with flamethrowers. Yes, you, as in your actual corporeal body. And yes, flamethrowers, like the kind that are on fire.
