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