Friday Night Funkin Online VS Hank Challenge is a free online rhythm game mod available at fnf.gosprunki.net. This mod pits players against Hank in an intense rap battle. The creator notes the difficulty of changing characters each turn, adding a raw charm to the experience. Based on the original engine by @cabalex (current version v25v4b).
The gameplay follows classic Dance Dance Revolution mechanics: press the correct arrow key (or WASD) when the scrolling arrow overlaps the target arrow. The goal is simple: hit the notes in rhythm and don't die. Controls can be customized in the options menu.
