Funkin

Funkin is the official open-source repository for Friday Night Funkin’, a popular rhythm game that combines catchy music with timing-based gameplay where players must hit directional cues to match beats. The project includes the full game source built using Haxe and OpenFL, allowing contributors and modders to explore and extend the game mechanics, audio library, and visual assets. In the core game loop, players navigate a story across multiple weeks with unique songs and characters, and the engine handles input timing, score calculation, and animated feedback in sync with background music. Because it’s open source, the community has created an expansive ecosystem of mods, new songs, and custom charts that extend replayability far beyond the base content. The repository itself is designed to be approachable for new developers who want to learn game development or contribute to the project, with build scripts, asset pipelines, and documentation to help users compile the game locally.
