So I'll just start off with the things I don't like, a lot of reviews said "this game was too easy compared to the first one" and I don't agree, because while it was not hard, sometimes you could be stuck the longest time over the most stupid thing, that feel when you have been trying to do something for 15 minutes just to realize the answer was right in your face doesn't compare to anything, so no it's not too easy, but it's too linear rather. And I'm not saying going chamber to chamber linear because that's what I expected when I bought the game, I'm saying that the non-portable surfaces in this game are ridiculous sometimes the puzzle is just finding the white wall to make the portal, the first time I played portal 1, specially in the last chambers I actually feel like there are a lot of ways to do the same puzzle, in portal 2 it may take you a while to do it, but once you do you realize that was the only way to go.
With that being said, the last chambers, right about the time you get the white gel, starts getting a lot better, since you can actually make more portable surfaces so you feel more freedom, and with that I move on to the next thing.
Characters, portal 1 had Chell and Glados and.... that's it, Glados was really funny and I certainly didn't expect the part where she tries to kill you the first time, but you can't really say any character is brilliantly written in portal 1, in 2 however we start off with Wheatley, and god I can't help but to laugh at most things he says. He is just so well written and has a brilliant VA, some goes for Glados and Cave Johnson and that makes it so that at almost every part of the game you are hearing an awesome character, the story felt much more immersive and well written.
I've also heard a lot of people complain about the lenght of portal 2 saying it was still too short, and personally while would love more content, I really don't see how valve could make the game any longer without it feeling tedious and repetitive.
About the Multiplayer Co-op I only had the chance to play the first 7-10 levels with a friend, and I just haven't have time since then but it's really fun, you can just play with a random stranger but playing with a friend and screwing up together just had me laughing the whole time.
And overall the game just feels good, even if you think some random chamber was too easy you still enjoy the game, or at least I know I did, definite well earned spot in GOTY and I would recommend buying it if you still haven't, the game went $7 on this Christmas sale so maybe you can trade a game with a friend for it.
I give it a 9.1/10
