Friday Night Funkin mashup is a free online rhythm game available at fnf.gosprunki.net. This chaotic mashup mod brings together multiple custom assets and characters from various creators.
Game progression includes: go to peeco pheely and bleemmed, then skoopieez north (with playful laughter "southhehehehehheheeheh"), and then paisen. The creator notes: "there's a problem with week 3, but idk what to do about it." The game text humorously includes "oh no."
