Canabalt is a side-scrolling "endless running" video game developed in 2009 by Adam Saltsman for the Experimental Gameplay Project. The player controls an unknown besuited man, fleeing an unknown threat. As the game begins we are introduced to the player character as he jumps from the window of an office building onto the roof of a neighbouring tower. The man runs forward automatically, accelerating as he goes. The player's only interaction is through the pressing of a single button to enable him to leap from building to building or vault over obstacles. Missing a jump will cause the man to fall to his death, while colliding with a crate or an office chair will reduce his speed. Bombs will also occasionally be dropped into the player's path.
