LOL this is so true. i just spent 5 hours on it, toying with all the devices, doing all kinds of experimenting. it's like crack!! my first level consists of physics-based puzzles. it starts off somewhat easy and then gets pretty Ttough as it goes on. i still have a ways to go though. LBP is such a creative game and now with the new water physics it makes things more interesting.
how much is the water update?
i think it cost around $5. It's pricey, i wish they would give it for free.
