I spent some time Playing Portal 2 today. It seems they kept the original spirit of the game in tact. I think it was originally meant to be a game marketed at girls and they kept the same dark, mean and manipulative humor that made the first game so fun.They didn’t mess with the game play but they did add some cool new features keeping the spirit of the first game. The early levels are really easy but I suppose that’s necessary for people who haven’t played before. It’s a real mind fuck the first time you play. Lot’s of fun.
