Well this is annoying... After unplugging my phone from my computer (or any USB, it gets stuck in an infinite loop of system notifications indicating 'USB connected/USB disconnected'. It won't allow the screen to stay off as long as the notifications keep pooping up, so the battery charge is suffering. :\
I used to think rpg's were kind of lazy when they recolored enemies or didn't animate them with a million poses. Though after dabbling with game dev I can see that it's a lot more realistic to work like that.
