i made a datastore script but the script didn't save any thing ??

this script is not saving any thing in real game and studio i enabled the api access and not working any one can help me

Here Is The Script:-

local currencyName = "Cash"

local expneededName = "ExpNeeded"

local expName = "Exp"

local levelName = "Level"

local breathingName = "HaveBreathing"

local birdName = "HaveBird"

local DataStore = game:GetService("DataStoreService"):GetDataStore("TestDataStore")

game.Players.PlayerAdded:Connect(function(player)

	local folder = Instance.new("Folder")
	folder.Name = "stats"
	folder.Parent = player	
	
	local currency = Instance.new("IntValue")
	currency.Name = currencyName
	currency.Parent = folder
	
	local expneeded = Instance.new("IntValue")
	expneeded.Name = expneededName
	expneeded.Parent = folder

	local exp = Instance.new("IntValue")
	exp.Name = expName
	exp.Parent = folder

	local level = Instance.new("IntValue")
	level.Name = levelName
	level.Parent = folder

	local havebird = Instance.new("IntValue")
	havebird.Name = birdName
	havebird.Parent = folder

	local havebreathing = Instance.new("IntValue")
	havebreathing.Name = breathingName
	havebreathing.Parent = folder
	
	local ID = currencyName.."-"..player.UserId
	local ID5 = expneededName.."-"..player.UserId
	local ID4 = expName.."-"..player.UserId
	local ID3 = levelName.."-"..player.UserId
	local ID2 = breathingName.."-"..player.UserId
	local ID1 = birdName.."-"..player.UserId

	local savedData = nil	
	
	pcall(function()
		savedData = DataStore:GetAsync(ID)
		savedData = DataStore:GetAsync(ID5)
		savedData = DataStore:GetAsync(ID4)
		savedData = DataStore:GetAsync(ID3)
		savedData = DataStore:GetAsync(ID2)
		savedData = DataStore:GetAsync(ID1)
	end)
	
	if savedData ~= nil then
		currency.Value = savedData
		level.Value = savedData
		exp.Value = savedData
		expneeded.Value = savedData + 20
		havebird.Value = savedData
		havebreathing.Value = savedData
		print("Data loaded")
	else
		-- New player
		currency.Value = 0
		level.Value = 0
		expneeded.Value = 20
		exp.Value = 0
		havebreathing.Value = 0
		havebird.Value = 0
		print("New player to the game")
	end
	
exp.Changed:connect(function()
     if player.stats:WaitForChild("Exp").Value >= player.stats:WaitForChild("ExpNeeded").Value then
      level.Value = level.Value + 1
      expneeded.Value = math.floor(expneeded.Value * 3) --You can change this if you want.
      exp.Value = 0 
	end
end)
	
game.ServerStorage.GiveExp.Event:Connect(function(amount,plr)
  if player.Name == plr.Name then
   exp.Value = exp.Value + amount
		end
	end)
end)
game.Players.PlayerRemoving:Connect(function(player)
	local ID = currencyName.."-"..player.UserId

	DataStore:SetAsync(ID,player.stats[currencyName].Value)
end)

game:BindToClose(function()
	
	-- When game is ready to shutdown
	
	for i, player in pairs(game.Players:GetPlayers()) do
		if player then
			player:Kick("This game is shutting down")
