If all die, script restart?

Hi, I have a round based game that teleports you once the intermission is over. I am very beginner at scripting, so I do not understand some of this. I want to make it so if everyone dies then the script goes back to intermission.

Here is the code I have right now:

local status = game.ReplicatedStorage:WaitForChild("Status")

while true do
status.Value = "Intermission (10)"
wait(1)
status.Value = "Intermission (9)"
wait(1)
status.Value = "Intermission (8)"
wait(1)
status.Value = "Intermission (7)"
wait(1)
status.Value = "Intermission (6)"
wait(1)
status.Value = "Intermission (5)"
wait(1)
status.Value = "Intermission (4)"
wait(1)
status.Value = "Intermission (3)"
wait(1)
status.Value = "Intermission (2)"
wait(1)
status.Value = "Intermission (1)"
wait(1)
target = CFrame.new(-131.76, 18.66, -120.07) --could be near a brick or in a new area
for i, player in ipairs(game.Players:GetChildren()) do
    player.Character.Head.CFrame = target + Vector3.new(0, i * 5, 0)
    --add an offset of 5 for each character
end
function setTeam(player, teamName)
    player.TeamColor = game.Teams[teamName].TeamColor
    if player.Character then --Just in case the character doesn't exist for some reason
    end
end
for _, player in pairs(game.Players:GetPlayers()) do
    setTeam(player, "Playing")
end
status.Value = "Round in progress..."
wait(200)
status.Value = "Time is up!"
wait(4)
end

It would be greatly appreciated if you helped me. Thanks!

To check if all players are dead, do this:

for _, player in next, game:GetService("Players"):GetPlayers() do
    if player.Character then
        if player.Character.Humanoid.Health == 0 then
            -- do code
        end
    end
end
