Friday Night Funkin is an open-source free-to-play rhythm-based indie game developed by Newground users, including ninjamuffin99 and KawaiSprite. The fact that the game is open source has made many FNF fans able to create new mods for the game. And this keeps the game always up-to-date. In the story of the game, The Boyfriend will have rap battles against characters who don't like him because he is dating The Girlfriend. Let's see what you can do on this journey.
