Makes my phone overheat and drains battery.

Definetly the best survival game for iOS. It has everything you would want from a survival game and then some. My only complaint is that when in the game, my iPhone 5s gets very very hot and drains the battery so fast that even with it plugged in and at 100% battery, it will go all the way from full power and turn off due to low battery. Keep in mind that my iPhone is less than a month old so Im not sure whats up with that.
