Staying outside for a long time has recently become very risky. It is not the sky that is falling, it is a huge rock, and if you stay there doing nothing for one more second, you may end up very poorly. Oh crap, skies are dropping more and more stones. What now? Try to predict places where these stones are going to land, and do not be there when the stones crushes the ground. Collect shields that will help you stay alive for a little longer, and gold coins to purchase interesting improvements. Have fun.
