Zombie, run! What am i doing wrong?

[mrmojorisin]

Morning all,
This app looks like fun but i can't seem to get it to work. Sometimes i choose my destination and i get green zombies that don't move, other times i get red ones that do...how do i play so i always get moving zombies?

The green ones havent detectet you yet. As soon as they see you they will chase you down.

Just increase theyr numbers if its too easy.

Remember, you have to move physically
