World of Goo is a point and click game with a very unique feel that can easily become addicting. It's a very original style of gameplay where you have to think of the physical interactions of the world. Gravity, wind, flamibility and friction will all come into play as you figure out how to get your goo balls through the world. There is also a bit of community play as you try to build the tallest tower with the extra goo balls you have saved. Some levels are a bit challenging until you figure out how some of the new goo balls react to things, but if you get stuck you do have the option of skipping that level. There are some amusing animated interludes between levels, sort of along the lines of the old pacman interludes that add a bit of story to the gameplay. I absolutely love this game and would recommend it to anyone looking for something different for a casual play.
