Thanks for bring this up.
I'd played the original World of Goo that was developed for the Contest, but never got around to getting the full version as I though it was Tad overpriced.
As I like to Pay for and support Independent Game developers, This offer Let me get a good game, and pay a reasonable (Though Lower) price.
I'll also suggest fans of independent games try out
Blurst Games. While they started out and still primarily focus on browser based games, they've recently started offering those as download ables, which has turned into quiet a time sink for me
