You were just getting "Aimbotted" because you dont know how to not get hit during that. Just about everytime jeff makes you float other enemys will spawn. You also had problems with the huge crowds but heres the thing. Theres alot of them because in order to not get hit by jeff you need to go behind them before jeff shoots you. If you do it correctly then you will survive and there wont be a huge mob trying to kill you. Another thing you can do is hide behind the ledge of the building but only do that unless you need to because jeff probably will be over there already so its more of a last resort if no one is close enough to hide behind before he shoots.
