Our friend and supporter of FSpaceRPG from way back released a kid friendly 2D game called Tang many years ago for the Mac. Its free to download and use. If its fun for your kids think of looking up the developers Paypal donation details and give him some loose change.
He was working on Tang 2, a significant overall which we were involved in the Beta testing for. And it was being made for Mac and Windows.
He needs your support to get this new title to market.
