I love the idea of it being an app for your phone so you dont forget the controller and I think its great that there are "missions." But I have a few things to suggest, first can you make more tricks, second please more missions, and third you should include a tutorial for tricks. And in the sphero box there should be a little ball that the droid can push around so people could have "Sphero Soccer."
