Friday Night Funkin (FNF) is a rhythm-based music game where players must hit music notes (arrows) in time with the beat to defeat opponents in rap battles. The game has gained a lot of attention for its catchy tunes, retro art style, and unique characters. The gameplay is relatively straightforward: you must press the corresponding arrow keys as they scroll down the screen in rhythm to the music.

FNF is structured around the story of Boyfriend, a character trying to win the affection of his girlfriend by defeating various enemies in musical duels. Each level introduces a new character who acts as a "boss" with unique songs and increasing difficulty.

The game is notable for its ability to blend fun, humor, and challenging rhythm gameplay, appealing to both casual players and rhythm game enthusiasts. Its charming pixelated art style and simple yet addictive gameplay make it a great pick for both short bursts of play and longer sessions.
