Clipping

Portal has been acclaimed as one of the most original games in 2007 despite being a comparatively short game. The game has received praise for its unique gameplay and darkly humorous story (created with the assistance of Erik Wolpaw and Chet Faliszek of "Old Man Murray" fame), the "character" of GLaDOS (voiced by Ellen McLain), and the final credits song, "Still Alive" (written by Jonathan Coulton for the game). The game's popularity has led to official merchandise from Valve as well as fan creations using elements of the game.
