The game is good, but the bugs make it almost unplayable

The concept is simply awesome, and the game could be very, very addictive. But Ive been playing it on an iPad Mini and I just cant play 2 missions on a row. It closes down unexpectedly and it loses my progress, because I cant save it on my own. Please fix it, there is so much potential in this
