friday night funkin is a rhythm game in which the player must complete numerous stages, referred to as "weeks," each of which contains three songs. Players face a different opponent each week, while some weeks have many opponents. During the game, the opponent will sing a succession of notes (represented by arrows) that the player must then follow with the arrow keys or the W, A, S, and D keys, or by using the mouse. You have complete control over how it is customized.
Some songs feature more complicated melodies, with the player's melody differing from the opponent's or both (the opponent and the player) performing a duet. Players can select one of three difficulty levels for each week: Easy, Normal, or Hard. The speed of the incoming arrows increases as the difficulty level grows, and the arrangement of the arrows becomes more convoluted. In the upper corner of the week selection screen, you may keep track of your scores. It displays the player's High Score for each difficulty for each week. There are two game modes in this game. In story mode, songs are played in a chronological order. Furthermore, the "free play" feature lets you to select any song from the game.
