Friday Night Funkin'

Free, open-source rhythm game by the Funkin' Crew (ninjamuffin99, PhantomArcade, evilsk8r, Kawai Sprite). Born from Ludum Dare 47, it became a viral hit: players face off in note-matching rap battles against a colourful cast of opponents, hitting arrows in sync with the beat. Playable free in-browser on Newgrounds and itch.io (HTML5) or downloadable for PC, with a mobile release (iOS/Android) shipping July 2025. The Kickstarter-backed 'Full Ass Game' remains in development. Full source lives on GitHub under Apache 2.0.
