Accidentally ran the iPad out of juice again yesterday. Same result as before.
Amusingly, got quite a run playing tonight, where I got the coin doubler like eight out of ten games. Have a feeling I'm not going to be happy when the other shoe drops, and I get a run like that of head starts. (Although one of the good things that it took me a bit to notice is that, with the newer missions, the head start isn't nearly as annoying. Not that it isn't frequently annoying, but there are a number of missions (fly above X zappers, zig-zag, don't hurt scientist for X meters, don't touch floor or ceiling for X meters) where it actually helps.)
