Why is immediately stopping the code while it is not supposed to?

I'm making a round system for a game and I made a game length variable to indicate when the time is up but right when it starts the game runs it even though there are 43 seconds left, Can anyone help me?

local gameLength = 43

for i = gameLength,0,-1 do

        for x, player in pairs(playersAlive) do
            if player then

                character = player.Character

                if not character then
                    -- Left the game
                else
                    if character:FindFirstChild("GameTag") then
                        -- They are still alive
                    else
                        -- They are dead
                        table.remove(playersAlive,x)
                        print(player.Name.." Has been removed!")
                    end
                end
            else
                table.remove(playersAlive,x)
                print(player.Name.." Has been removed!")
            end
        end

if i == 0 then
    status.Value = "Times up!"
    wait(2)
    break
end
