v1.01 Tutorial update and clarification

Based on early feedback, the tutorial confused some people - more specifically, the initial step where you learn how to drive around the planet. The player is meant to drive around for a bit, and once they're below 100 food, the next step of the tutorial pops up automatically. It seems I made this step too long, though, because several players couldn't figure out how to advance the tutorial and thought that they were missing something.

To rectify this, I've changed it so that the tutorial now advances once the player drops below 140 food. Hopefully this will make things less confusing.
