World of Goo

World of Goo is a puzzle game developed and published by 2D Boy (currently known as Tomorrow Corporation). It was released in October of 2008 on Microsoft Windows and the Nintendo Wii and has been released on other consoles in later years.

Plot
Pipes suddenly appear around the land and the goo galls go to investigate where they lead to. It is later revealed that the pipes lead to "The World of Goo Corporations" factory, where they using the goo balls as an alternative source of power. The goo balls have to find a way to destroy the factory and explore distant lands in doing so. The goo balls get around by building bridges and towers out of goo to avoid obstacles and make it to the exit.

Why It Rocks

 * 1) Unique concept for a puzzle game.
 * 2) Phenomenal music that displays a range of emotion.
 * 3) Great graphics that gives the game its indie feel.
 * 4) Level design helps players learn basic concepts earlier in the game and offers quite a bit of challenge later in the game.
 * 5) Has traditional puzzle game elements but also employs physics and fast acting which are rare in puzzle games.
 * 6) Creative (and sometimes strange) concepts in levels. For example, in one level you have to light your own goo balls on fire to blow up a robots head that is blocking the exit.
 * 7) Bizarre level zones, ranging from cyberspace to inside of a monster's stomach.
 * 8) Allows for a margin of error, not all goo balls need to make it to the exit alive.

Bad Qualities

 * 1) Difficulty curve is a little steep. One of the hardest levels being only in world 2.
 * 2) Game can be beaten within a few hours.
 * 3) Plot is a little hard to follow.
 * 4) Accidently clicking on a "Time Bug" is not uncommon while building.

Reception
World of Goo has a 9/10 on Steam and won the VGX Best Indie Game of the Year Award in 2008 as well as the IGN Wii Game of the Year Award (Also in 2008).
