Walker is a sidescrolling shoot'em-up game for Commodore 64, written by Sven Forstmann. The players controls a creature that can walk, jump and shoot. The longer the player walks into the game, the more enemies to shoot or avoid, like stoneblocks, bees, bubbles and birds. The player does not get points for shooting enemies, only for the distans walked. The aim is to get as high score as possible.
