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.
It's very hard not to give this game a perfect score. It's got that strange addictive quality like when you pick up a rubick's cube and start trying to solve it. In this game you experiment by building different structures out of sticky goo balls in an attempt to reach the goal. The game has plenty of levels and it manages to feel fresh all the way to the very end. If you don't already own this game 5 times from all the Humble Indie Bundles it's been in, definitely buy it.
This is one of the best indie games I have (that says a lot because I've all the humble humble, indieroyale and indiegala bundles + some other indie games).
It works on my 4 year old netbook with ubuntu. It has good artwork, great astetics and a fantastic soundtrack.
The controls are simple and they work good, but I recomand using a regular mouse instead of a touchpad.
The only downside for me is that the time to beat the game is not very long.
With games as popular as World of Goo, it's hard to add anything new to what was written over and over again.
If you haven't heard about it yet, you live under a rock and should try it.
One of the most refreshing new titles in the past years that proves indie ingeniutiy beats wads of cash in quality any time.
