How to make a start GUI not show when a player resets? (UNANSWERED)

I'm finished with my start GUI, except there's one problem : It shows whenever a player dies. Here's my script so far (I probably will need to insert a new script for that :c)

--Script by club101coolguy

local Player = game.Players.LocalPlayer
Box = script.Parent.Parent.Frame
Play = script.Parent.Parent.Play
gui = script.Parent.Parent
Text = script.Parent.Parent.TextLabel
local Sound = Instance.new("Sound", gui)
Sound.SoundId = "http://www.roblox.com/asset/?id=221235033"
Sound.Pitch = 1
Sound.Volume = 0.7

--Variables and Variable Properties

Sound:Play()

function MouseEnterPlayButton()
    Play.FontSize = "Size48"
end

function MouseLeftPlayButton()
    Play.FontSize = "Size36"
end
Play.MouseEnter:connect(MouseEnterPlayButton)
Play.MouseLeave:connect(MouseLeftPlayButton)

--Makes chat Play Button bigger when a mouse hovers.

function PlayGame()
    Box:Destroy()
    Play:Destroy()
    Sound:Stop()
    Text:Destroy()
end

Play.MouseButton1Down:connect(PlayGame)
--When a Player clicks on Play, Music stops and GUIs dissapear.
