Just talking about the mechanic doesn’t do justice to this game. Portal has a quality that I can only attribute to its indie roots. The attitude of the game, the wit, its focus are unlike any I’ve seen in a long time. Some critics decry the length of the game, but I disagree totally. The length of the story is perfect. Portal is a dazzling short story in a sea of mediocre novels — fast paced, intense, and full of surprises, the story kept me going straight through until I hit bed. If Jean Paul Sartre wrote stories for video games, this would be a good candidate for him.
