Okay, quick runthrough. You see the value labelled "Nutrition"? That's how full you are. Don't let it drop to zero, or you'll starve to death. Don't worry, there'll be an opportunity to tank up along the way.

Then there's your score. Pretty self-explanatory.

At times you will have to continue by using an item. For instance, to fire a gun click on the gun in your inventory then click "Use Item". Also, using an item at the righ time may open up new options.

Oh, and one more thing. You may have killed all the zombies that were trying to eat you, but be wary, a few may still be left.

SCORE is 0.
