This is stupid!!! After spending so many hours killing zombies and gathering many supplies to repair the equipment at the base camp I pressed the menu thinking it would pause while I did some chores. After some 10 minutes I turn back to the game and see i died of hunger and lost everything I had worked for. Because the stupid game keeps playing in the background instead of pausing as any normal game should!!!!!!!!! Then I would've had to wait for hours for my energy to refill. Uninstalled!!!!!!!
