Fract OSC (stylized as FRACT OSC) is a music-based puzzle game created by independent game developer Phosfiend Systems. The game was released on 22 April 2014 for both Microsoft Windows and OS X platforms. Fract OSC allows players to explore an abstract landscape that includes puzzles using platforming and music-based game elements. Completing these puzzles creates ambient music that continues to play in the environment and unlocks portions of an in-game music synthesis that allows players to create their own music.
The game, originally named "Fract," was developed by Richard Flanagan as part of his student work at the University of Montreal and achieved wide interest after winning the Student Showcase award at the 2011 Independent Games Festival and release of a freely available demo. Flanagan brought aboard Quynh Nguyen and Henk Boom to flesh out the game, branding themselves Phosfiend Systems. They received funding help from the Indie Fund to complete the title. The game was originally planned to span several levels, but due to complexity, it was reduced to a single primary level representing a synthetic oscillator, shorted to "OSC" for the game's final release.
