Audiosurf

Background:
Audiosurf is an award-winning puzzle-rhythm hybrid game. Its track-like stages visually mimic the music the player chooses, from his or her own library, while the player races across several lanes attempting to create patterns and pairs by collecting colored blocks that appear in sync with the music.

Gameplay:
Players control a levitating spaceship-like craft similar to those found in Wipeout or F-Zero. The player maneuvers it down a colorful multi-laned highway, collecting blocks. The ship is controlled either by a mouse, the arrow keys, the number keys, or an external gamepad.
