Audiosurf

Audiosurf is a 2008 music-based puzzle video game created by Invisible Handlebar, a company founded by Dylan Fitterer. Its track-style stages visually mimic the music the player chooses, while the player races across several lanes collecting colored blocks that appear in sync with the music. The game was released on February 15, 2008, over Steam, a few days after winning the Independent Games Festival 2008 Excellence in Audio Award, heavily influenced by the soundtrack composed by Pedro Macedo Camacho. The full version was for a long time only available for purchase through Steam, but was later released as a retail product in Europe, by Ascaron. Audiosurf was the first third-party game to use Valve's Steamworks technology. The Zune HD version was also released as Audiosurf: Tilt. A sequel, Audiosurf 2, was released in May 2015.
