I've had a lot of fun with this game as well.
But has anyone noticed any random crashing to homescreen? My first crash was when my battery was getting fairly low, so I was afraid that had something to do with it. But then even after recharging some I got more random crashes. I re-enabled wifi and haven't had a crash since...
That kind of makes me curious what is going on... but I haven't looked into it further yet, so don't mean to raise any alarms.
Throughout all this though it has not corrupted my save data or anything, at least as of yet *knock on wood*. I think it was Asphault 7 that one time I got a phone call in the middle of gameplay and it crashed the game and corrupted my save data >_> I had some backups though, but lost some progress.
