brick onTouch debounce only for 1 person?

This brick makes GUI debounce for all players which means if 1 person steps on it and it shows it to him, for the other person it won't because debounce is equal to true. How would i make it so debounce is per person so more than 1 person could step on a brick and it would still show it to him?

debounce = false

script.Parent.Touched:connect(function(hit)
if debounce == false then
debounce = true
local humanoid = hit.Parent:FindFirstChild("Humanoid")
if humanoid then
local player = game.Players:GetPlayerFromCharacter(hit.Parent)
player.PlayerGui.Intro.Window.Text.Visible = true
player.PlayerGui.Intro.Window:TweenPosition(UDim2.new(0,0,0.5,150))
player.PlayerGui.Intro.Window.Text.Text = "Remember what i said? Red bricks are a no no. Try to avoid them as much as possible! (Hint: They kill you) ~NonSpace"
-- first time learning Tweening!
wait(10)
player.PlayerGui.Intro.Window:TweenPosition(UDim2.new(0,0,0.5,400))
wait(1)
player.PlayerGui.Intro.Window.Text.Visible = false

debounce = false
end
end
end)

-- Only works for the first person :(
