Debounce not working for key inputs?

I tried to set up a debounce for whenever the mouse button is pressed, but for some reason it just keeps repeating the code, completely ignoring the debounce. Is there anything I did wrong here?

--Variables
local folder = script.Parent
local player = game.Players.LocalPlayer
local rf = script.Parent:WaitForChild("RemoteEvent")
local chargeRemote = script.Parent:WaitForChild("Charging")
local fireRemote = script.Parent:WaitForChild("Fire")
local shooting = false
local uis = game:GetService("UserInputService")
local mouse = player:GetMouse()
local character = player.Character or player.CharacterAdded:Wait()
local hum = character:WaitForChild("Humanoid")
local holdingMouse = false
local debounce = false

--Anims
local charge = folder:WaitForChild("Charge")
local fire = folder:WaitForChild("Fire")
local chargeTrack = hum:LoadAnimation(charge)
local fireTrack = hum:LoadAnimation(fire)


--Functions
if not debounce then
	uis.InputBegan:Connect(function(input, gameProccessedEvent)
		if input.UserInputType == Enum.UserInputType.MouseButton1 then
			debounce = true
			print("working")
			wait(.2)
			local rh = character:WaitForChild("RightHand")
			holdingMouse = true	
			chargeTrack:Play()	
			rf:FireServer(rh, character)
			
			--Charge the ki
			rf.OnClientEvent:Connect(function(cb)		
					
			--[[chargeTrack.KeyframeReached:Connect(function(pose)
				if pose == "Pause" and holdingMouse then
					chargeTrack:AdjustSpeed(0)
				end
			end)]] 	
					
				if holdingMouse then
					while holdingMouse do
						wait()
						--chargeRemote:FireServer(character)
					end
				end
			end)	
			
			--When the mouse is released, fire
			mouse.Button1Up:Connect(function()
				--[[if chargeTrack.Speed == 0 then
					chargeTrack:AdjustSpeed(1)
				else
					return false
				end]]
				
				while chargeTrack.IsPlaying do
					wait()
				end
				holdingMouse = false
				fireTrack:Play()
			end)
		end
	end)
end
