It's cool. Overall I think this is a good game, but some stuff holds it back from me liking it as much as the first game. I feel like the puzzles in the second half/last third or so of the game, end up being pretty tedious and annoying to solve. It doesn't help that the environments often feel cluttered, and I often don't even see all of the pieces of the puzzle, to know that they're relevant for what I need to do in order to solve it. Also the game's writing... is generally good, but I got kind of a Pixar vibe from it at times, which was a little off-putting. Overall though, I think Portal 2 is good. It'll probably click more with some players than it did with me.
