The game restarts after one player dies. Why is this happening?

I am creating a round script for my game and I am stuck. I want to know how all players will return to the lobby after they are killed, but the round only restarts after one player is killed, and the time also freezes for other players that are still alive in the game/round. Why is this happening? I just want to get to the point of the script.

while true do
    wait(1)
    ftime = ftime - 1
    text.Value = "Time: ".. ftime
    Playing = workspace.Players:GetChildren()

if #Playing == 0 then
    for _, v in pairs(workspace.MapFolder:GetChildren()) do
        v:Destroy()
    end
    break
end

if ftime == 0 then      
    for _, v in pairs(workspace.MapFolder:GetChildren()) do
        v:Destroy()
    end
end

for _, v in pairs(game.Players:GetChildren()) do
    if v.Character.Humanoid.Health == 0 then
        workspace.Players[v.Name]:Destroy()
        end
    end
end
