Great and smart, but way too short

User Rating: 8 | Portal 2 PC
This game if great, while it lasts. The concepts are great, the play is great, the puzzles are very good. The humor is fun and keeps you wanting more. But just as you feel like things are starting to hum and you are getting into the game, its over. In fact, if not for a couple spots where you have to sit and think for a long while to figure out how to get off a level, it would be over in an afternoon. The hole game should be the first level. It should be at least 4 times as long as it is. Really, the game is a 10 for the part you get to play, but its so short it cant get that rating, its almost a demo. I literally am waiting until I forget the puzzles so I can play it again. I think if they took this idea, added to a full blown story like half life and add this in as part of a bigger game, it would make more sense.
