Edge Extended is a sequel to the original Edge. The game plays mostly the same as the original. The player controls a rolling cube, which has to be navigated through a geometric universe as fast as possible. Around each level there are prisms that the player can collect. This version of the game includes 48 new and unique levels (plus some bonus levels) that are created in a new 3D engine. The new engine allows for multiple perspectives and it is possible to rotate the view. There's also a new ghost mode that allows the player to compete against a ghost of his own best runs. New to the gameplay is the introduction of a black cube that interacts with the levels on its own by triggering switches. The game also has a new soundtrack consisting of 23 unique tunes.
