I have a few questions, if you have the time and don't mind. Games are often pointed out as particularly harder on Android because of the multitude of devices with different levels of graphics support. Did you have trouble reaching most of the market? If you did, how did you solve it? I can also imagine some stuff like Samsung's Multi Window tool causing problems. Did anyone report that?
