Portal is a first-person puzzle game. Players must solve physical challenges by opening portals to maneuver objects, and themselves, through the enigmatic Aperture Science Laboratories.
what to say? this game is not challenging at all, completely boring and waaaay too short.
After 90 minutes of playing, just when i asked myself "when is this stupid tutorial over, i want puzzles!" the credits appeared and the game was over. it was really disappointing. the only thing that kept me from smashing my computer was this funny "still alive" song that was played in the credits.
that song is the only positive thing about this game. and certainly not worth 20 bucks.
