I realize this is an old game and its third incarnation is about to come out, but dang this was fun! It was challenging, fun to look at, and had a great soundtrack and excellent replay value. The only complaint? Too short. But again with the replay value.
The Plot: You roll your giant sticky ball around and things stick to it. Things like cows and penguins. Eventually buildings.
Why would you do this? To make stars out of your giant piles of stuff. Duh!
