Friday Night Funkin' Windows, Mac, Linux, Web, Android game

Friday Night Funkin' is a rhythm game in which the player must pass multiple "weeks", each usually containing multiple songs. Each week, the player typically faces a different opponent.

During gameplay, the opponent will sing a pattern of notes which the player must mirror by pressing the arrow keys or the keys W, A, S, and D. Later songs introduce more complicated patterns, with the player's pattern varying from the opponent's or both singers engaging in a duet. At the bottom of the screen is a bar indicating how well the player is doing. The left side of the bar is red, representing the opponent. The right side is green, representing the player. Successfully hitting notes will increase the size of the player's bar, while missing notes or pressing when there are no notes will cause the opponent's bar to expand. The player fails if the opponent's bar fills up the entire bar.

For each week, the player has the option to select one of three difficulties: Easy, Medium, and Hard. As the difficulty increases, the speed of incoming arrows increases and the patterns of arrows become more complicated. The player's high score for each week on each difficulty is tracked and shown in the top corner of the week selection screen.

The player can also play in "free play" mode, where the "week" structure and any cutscenes are ignored and the player can play any individual song on its own.
