The rules sound good. And when you're found, you should just go to the elevators and wait for the others. AND NO GIVING HINTS!!!!!!!!!! That just ruins the game...
Though, I think the seeker(s) should be able to have one cheat, that they could ask a random person in the mall if they saw any of us! Just imagian the reactions!!!!!!! And if the person they ask doesn't know, then they're not aloud to ask another. ONLY ONE!
