I don't agree with the 'no time limit' part... some people will just hide very far and keep running and it will make the game last forever... I think I get what you're trying to solve : the fact that with that few people they're all spread out and sometimes can't find each other to get a kill... But if there is no time limit at all, the people won't even search for each other, hoping the others will kill themselves... I say make the time limit for that part longer, like 10 or 15 minutes..
