Why does it take so long for the next part to be touched by a player with the script I made ?

So I made a script where the tiles disappear and disable can collide after the touch event gets triggered by the client touching it. The script went fine for the first tile to be touched but after the first one, it takes a long time for it to disappear and disable can collide after it's being touched.

local tiles = game.Workspace.Tiles:GetChildren()
local debounce = true
for i, v in pairs(tiles) do
v.Touched:Connect(function(hit)
		local player = game.Workspace:FindFirstChild(hit.Parent.Name)
		print(player)
		if player then
			if debounce == true then
				debounce = false
				v.Transparency = 0.5
				wait(1)
				v.Transparency = 1
				v.CanCollide = false
				wait(3)
				v.Transparency = 0
				v.CanCollide = true
				debounce = true
			end
			
		end
	end)
		
end
