debounce only works once, then player can spam key. what's the issue?

the player presses and holds F, animation and other things go on in the background. then there is a cooldown. after this cooldown the debounce doesn't do it's job any more. how do i fix this?

local UserInputService = game:GetService("UserInputService")
local Player = game.Players.LocalPlayer
local mouse = Player:GetMouse()

local KeyPressed = false

repeat wait() until Player.Character
c = Player.Character
humanoid = c.Humanoid

local Time = 0
local Debounce = true

--animation codes

	local holdAnim = Instance.new("Animation")
	holdAnim.AnimationId = "http://roblox.com/asset/?id=4896264874"
	local holdTrack = humanoid:LoadAnimation(holdAnim)

	
	local chargeAnim = Instance.new("Animation")
	chargeAnim.AnimationId = "http://roblox.com/asset/?id=4896212792"
	local chargeTrack = humanoid:LoadAnimation(chargeAnim)

	local releaseAnim = Instance.new("Animation")
	releaseAnim.AnimationId = "http://roblox.com/asset/?id=4896256143"
	local releaseTrack = humanoid:LoadAnimation(releaseAnim)

--function

UserInputService.InputBegan:Connect(function(input, gameProcessed)
	if Debounce == false then return end
	if input.KeyCode == Enum.KeyCode.F then
		KeyPressed = true
		Debounce = false
		
		local BG = Instance.new("BodyGyro", c.HumanoidRootPart)
		BG.maxTorque = Vector3.new(250000,250000,250000)
		BG.CFrame = CFrame.new(c.HumanoidRootPart.Position, mouse.hit.p)
		BG.P = 20000
		local BP = Instance.new("BodyPosition", c.HumanoidRootPart)
		BP.maxForce = Vector3.new(math.huge, math.huge, math.huge)
		BP.Position = c.HumanoidRootPart.Position
		
		chargeTrack:Play()

spawn(function()
		while KeyPressed == true and Time < 200 do
			wait()
			BG.CFrame = CFrame.new(c.HumanoidRootPart.Position, mouse.hit.p)	
			Time = Time + 1
			print("Key being held interval: ")
			holdTrack:Play()
			holdTrack.Looped = true
		end
		if KeyPressed == false or Time >= 200 then
		Time = 0
		holdTrack.Looped = false		
		releaseTrack:Play()
		wait(0.5)
		BG:Remove()
		BP:Remove()
	end
end)

UserInputService.InputEnded:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.F then
		KeyPressed = false
		print("Key has been let go of")

			wait(5)
			Debounce = true
		end)
	end
end)

    if input.KeyCode == Enum.KeyCode.F then
        KeyPressed = false
        print("Key has been let go of") 
         wait(5)
            Debounce = false
            end
            end
        end)
    end
end)

try setting debounce to false
