World of Goo is a charming puzzle game. Your goal in each level is to get as many Goo Balls to the exit as you can, with the catch being that they’re also your resource, and you can’t avoid sacrificing some to save the rest. So, it’s all about optimizing your strategies and minmaxing. As you go on the complexity increases, you encounter different kinds of Goo Balls with different properties, unlock an ability or two.
To advance you need to rescue a set minimum number of Goo Balls (most of the time), but to really complete them you’ll have to make a much harder OCD threshold. It caused me some figurative headache with certain levels and made me turn to guides.
Surprisingly, there’s even a bit of a story, and, while vague, it helps keep you engaged. The game’s fantastic as it is, but the fact that you’re moving towards something with things happening around you is like the icing on the cake.
For those brainy enough to take on the OCD challenges, and for those who aren’t completionists World of Goo will most likely be a perfect puzzle game experience… otherwise it’ll be near-perfect. It’s a very good game either way.
