The App has been out for a couple of days. Apple's sales reports are delayed for yesterday so we're not sure how much Chris has made yet. While it was free it made top 25 puzzle and arcade games in 3 stores and top 100 puzzle and arcade in a couple more including the US!
It has actually only been out for a few days. It was free for the first couple, and the app made it into the top 50 puzzle games in the US and onto charts in some other countries. Following that, I decided to make it paid. The numbers for paid downloads are still rolling in, but it looks promising.
