How to fix IntValue resetting when game is stopped?

I am trying to use a datastore but it is always storing the wrong value (0) instead of what I earned (125) (Tested in Studio and Roblox, you can see the game here) "Allow studio to access API services" is enabled My code:

local DataStoreService = game:GetService("DataStoreService")
local dataStore = DataStoreService:GetDataStore("GAME")
local p

game.Players.PlayerAdded:Connect(function(player)
    p = player
    local coins = Instance.new("IntValue")
    coins.Name = "Coins"
    coins.Parent = player

    local userid = "Player_"..player.UserId
    local data1
    local success, err = pcall(function()
        data1 = dataStore:GetAsync(userid.."-coins")
    end)

    if success then
        print("Load success!")
        if coins then
            coins.Value = data1
            game.StarterGui.ScreenGui.TextLabel.Text = coins.Value
        end
    else
        warn("Failed to load data: "..err)
    end

end)

function remove(player)
    local coins = player.Coins
    local val = coins.Value
    local userid = "Player_"..player.UserId
    local success, err = pcall(function()
        dataStore:SetAsync(userid.."-coins",val)
    end)
    if success then
        print("Save success. Data: "..val)
    else
        warn("Save failed. Error: "..err)
    end
end

game:BindToClose(function()
    remove(p)
    wait(2)
end)
