I liked playing it with my pc. I saw it for Wii and since a while it´s also porterd to android. It´s a lot fun playing on a smartphone.
You can get a demo version or a full version.
The forum is pretty quite at the moment but they shared a lot custom level. Not sure if you can play them with the demo.

The full version World of Goo is free on the Amazon Appstore at the moment.

It's a great game. I used to play it all the time.
