For version 139: In easy and tough modes, you must travel a certain number of miles to reach safety. "Miles to safety" will be displayed at the top left of your screen (when in "Navigate" mode, I believe).

If you are playing "extreme" mode, the screen will only say how many miles you have wandered. You need to travel approximately 700 miles (or more) without dying to beat extreme mode.
