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

		local d = Instance.new("Part", Workspace)
		d.Size = Vector3.new(5, 5, 1)
		d.CanCollide = false
		d.CFrame = Player.Character.Torso.CFrame*CFrame.new(0, 5, 0)
		d.Transparency = 1
		game.Debris:AddItem(d, 5)
		RS = Player.Character.Torso["Right Shoulder"]
		for i = 1, 15 do
			RS.C0 = RS.C0 *CFrame.Angles(-0.1, 0, 0)
			wait(0.01)
		end
		LS = Player.Character.Torso["Left Shoulder"]
		for i = 1, 15 do
