Portal 2 - Update

Okay, I've had the game for just over a week now, and I'm still enjoying it as much as when I first got it, but man its getting harder and harder. The puzzles in Chapter 7 were by far the hardest so far. The reason it's gotten so much harder is because they introduce more variables into the maps. Although often times there is only one way to solve the puzzle it can be tricky to fine the solution (or way out). At this point you have the portal gun, the cube and three different liquids. A blue one and orange one and a white one. The blue is a bouncy substance, orange is like a oil slick which allows you to run super fast and white changes the properties of almost any surface so you can create a portal. If it sounds weird and complicated it sort of it. But despite what I'm saying the story moves along really well, the writing is touch notch and very funny and over all it is the best game of the year so far. Now if I can just finish the thing.
