Why doesn't this game-ending script end the game?

This is a section of a script for a round system.

local roundlength = map:FindFirstChild("Time").Value
        local canwin = true
        local playingchars = ingame:GetChildren()
        local gameongoing = game.Workspace.GameOngoing
        gameongoing.Value = true
        if map:FindFirstChild("Genre").Value == "Survival" then
            if map:FindFirstChild("Game") then
                map:FindFirstChild("Game").Disabled = false
            end
            local gamescript = map:FindFirstChild("Game")
            repeat
                wait(1)
                roundlength = roundlength - 1
            until #playingchars == 0 or roundlength == 0
            gameongoing.Value = false
            gamescript.Disabled = true
            if #playingchars == 0 and roundlength > 0 then
                message.Value = "Nobody survived!"
                wait(5)

This part of the script is supposed to end the round when everyone is dead. The "playingchars" variable is all of the character models in the ingame folder ie. the players that are alive and playing the round. The "gamescript" variable is the script inside the map which controls the round and allows for it to work. The "roundlength" variable is the length of the round which counts down until either everyone is dead (the number of playingchars is 0) or until it reaches 0, at which point the gamescript is disabled.

The condition at the bottom is meant to be met which all players are dead and there is still time remaining, however after testing it multiple times, the round simply continues after I die.

I made a similar script for a similar game a while back and it worked fine:

if map:FindFirstChild("Type").Value == "Survival" then 
            if map:FindFirstChild("Game") then
                map:FindFirstChild("Game").Disabled = false
            end
            message.Value = "Time left: "..roundlength
            wait(1)
            repeat
                roundlength = roundlength - 1
                message.Value = "Time left: "..roundlength
                wait(1)
            until roundlength == 0 or #ingame:GetChildren() == 0
            if map:FindFirstChild("Game") then
                map:FindFirstChild("Game").Disabled = true
            end
            if #ingame:GetChildren() == 0 and roundlength > 0 then
                map:Destroy()
                message.Value = "No one won :("
                wait(3)

Not too sure what I'm doing wrong here.
