"World of Goo is a physics based puzzle / construction game. The millions of Goo Balls who live in the beautiful World of Goo don't know that they are in a game, or that they are extremely delicious."And that's what it is - this is not just a game, this is a fictional world with a great story, beautiful cartoony 2D graphics and phenomenal gameplay. Your goal is to get delicious balls of goo to a pipe, which is usually on the opposite side of the level. You do this by making a bridge, tower or another similar structure, with the help of which remaining goo balls can travel to the pipe. Of course there are many variations to the theme and I can assure you that during the course of the campaign you won't get bored. The pipe takes them to the World of Goo corporation, where you can build a huge tower and compare it to other builders from around the world.

The amount of attention to detail in this game is amazing, especially for an indie developer. Even though the graphics are beautiful and physics are all-present everything runs smoothly, even on a lower-end machine such as a netbook. The game menu is special and a great introduction to the world. Gameplay runs flawlessly and each mistake is your own fault (I've never failed due to a bug or glitch). During the game you get surprised by many treats, but... I won't spoil the game for you. Let's just say they'll make you open your mouth and stare. Oh, and for perfectionists there is OCD - a goal to complete every level without wasting a single ball of goo.
There is so much to say about this game that I could go on writing about it for hours. If you want to read more glowing reviews, just do a Google search. The simple truth is that the game is great in all aspects. Things that should be mentioned to do it justice is a great learning curve (difficulty increases through the game and there are levels where you are forced to flex your brain quite a bit) and one of the best executed stories in years. You won't feel sorry for the time you invested in this game, which is rarely the case with today's games. I cannot recommend this game enough, and if you can spare the money, you should definitively buy this game - for your own goo:)
