World of Goo

World of Goo is a puzzle game that was created by 2D Boy, a duo of game developers, consisting of Ron Carmel and Kyle Gabler. The games' main objective is to get a certain amount of goo balls into a pipe that represents the exit. In order to do this, you must create various building, bridges and structures to overcome gravity. Many objects and obstacles, such as spikes, cliffs and hills are in your way and must be overcome. Every extra goo ball that you manage to get to the exit, will be transferred to a sandbox area, which is called 'The World of Goo Corporation'. In this area you will be playing against other players from all around the world, trying to create the tallest structure/building possible.

In World of Goo there are four chapters and an epilogue, and each has a certain number of levels. Each chapter is equivalent to one year. You will start in summer and you will finish the chapter when it is spring. The fourth chapter is set in a virtual world where there are no seasons. The game has a total of 48 levels including the 'World of Goo Corporation' level. There are many different types of goo and each has different characteristics. For example, there is a 'Water Goo' that is able to form long chains of goos and a 'Pokey Goo' that can connect with 4 other goos and many others.
