Missing key iOS features

My son loves the software but he also loves periodically pressing the home button. Software since iOS 4 has supported resuming after being minimized. This app though? Nope. Seriously, apparently the basic work to save state is too much to ask for a $3 software that purports to have sold half a million copies. Hire an intern or something what a odd year+ long oversight.
