Portal 2, compared to the first game, is longer and more linear, the focus this time being the story and characters. Because it's longer the tests had to be shortened a bit and because of that it may feel like they're easier than the ones in Portal 1. But don't worry, if you feel unsatisfied and want more action there is co-op mode to ease your hunger for testing and the community maps that are available from the start(they also come with a level editor so you can make your own levels if you want).
