Yup, Feed My Zombie was approved after only 4 days! It's available in the app store now, although the release date was for the 22nd (it's the 22nd for my time zone but I was assuming they went by Apple's clocks and/or wouldn't release it until later in the day). Good news all around.
I'm already working on a couple of bug fixes that I didn't catch until after I submitted it, along with Game Center achievements, and 30 winter themed levels that will be available in early January.
