Can I make a damage script with BoolValue that damages everyone who touches the part?

I've made a script which damages the player that touches the part, but only the 1st one of them...Is it possible so I can damage evryone it touches witha bool value in the part?

wait(3)
local debounce =  false
Player = script.Parent.Parent.Parent
n = script.Parent
mouse = Player:GetMouse()
run = game:GetService("RunService")
duh = 0

function pizza(mouse)
    if debounce == false then
        debounce = true

        d.CanCollide = false
        d.CFrame = Player.Character.Torso.CFrame*CFrame.new(0, 5, 0)
        d.Transparency = 1
        game.Debris:AddItem(d, 5)
