Friday Night Funkin' is a musical rhythm game in which you participate in free and unique musical fights to see how well you know your music.
The player takes control of Boyfriend, a character who must fight a succession of opponents in order to keep dating his significant other, Girlfriend. The player must complete a series of stages, known as "weeks," each of which contains three songs. Every week, the player meets a new opponent, however, some games break from this pattern by including many opponents. During games, the opponent will sing a sequence of notes (represented by arrows) that the player must imitate using the arrow keys or the W, A, S, and D keys. Some songs feature more difficult patterns, such as when the player's pattern differs from the opponent's or when both vocalists perform a duet.
Each week, the user can choose from three different difficulties: Easy, Normal, or Hard. The speed of incoming arrows increases as the difficulty level rises, and the arrow patterns get more intricate. The player's highest score on each difficulty for each week is tracked and shown in the upper corner of the week selection screen. The game has two separate modes of play: a story campaign in which songs are played in a linear order, and a "free play" option in which any of the game's music tracks can be selected at any time.
WASD/Arrow keys.
