I just submitted our first iPhone game for approval at the Apple App Store. It's a game called LetterWriter:Oceans, and it's an educational app that helps kids learn how to draw the capital letter glyphs in a fun undersea environment. Follow the link for more screenshots.
We've been working on this for several weeks, because we have a child who is just learning to write, and we've been unhappy with the quality of iPhone apps out there for this. So, for our anniversary, my wife and I took a vacation up to Cloudcroft and designed the game we wished was available, and now it's done.
Watch for it at the app store in a couple of weeks.
