I'm not sure if anyone's heard of this, but it's a great little casual game for everyone, even the kids. It doesn't take very long to play, and it's fun to do while you're waiting for that next BFG download to finish.
It's from a small New Zealand company called Tricky Sheep, and they said they want to bring a version to Big Fish in 2009. I would suspect it would have to be a good deal larger for that, but this would make a nice chapter. (It took me under 20 minutes to finish it, but it was charming and diverting.)
It's here:
