The title says it all: Canabalt HD is Canabalt in HD! The epically popular one button running game that originally appeared in browsers back in 2009 has made its way to the mobile scene before. There's even C64anabalt for the Commodore 64! Now, with bigger, more powerful mobile devices around, this high-definition version of the game comes along, featuring remade 3D backgrounds and smoother animation. Don't worry, though. It's still just as easy to leap out a window and smack into another building!
