Hi all, this is my first iOS game. I have had the idea in my head for over 5 years (you can even play a version of this from back then online here
http://ideationapps.com/2birds/2birds.html - but the web based version is terrible compared to the polished iOS version - not just graphically, but gameplay too). I finally had enough motivation to jump through all the hoops to get it in the App store.
There are a few other things on the site giving technical information which might be interesting too, but you can judge that for yourself.
