This game is based on "avoid the crowds there is always someone infected" but how the hell would they let a man who's got a bite to enter a bus or a elevator? And way too much ways to die, basically this game is a straight lucky line.
I spent at least half an hour at level 30 trying to do everything while dodging the bullets, then i decided to jump to suicide and skip the level AND THE SHOOTER DIED. WAS IT ALWAYS THAT SIMPLE?
After getting to the point when I can one-shot the last planet, I came back to "Penguins can't fly" to destroy it thousands of times. Just for satisfaction.
