Help with memory optimization

[lone mountain]

im working on a game recently but i notice that the longer player play the game , the higher the memory get so how do it fix that ?

[final dove]

local part = Instance.new("Part")
part.Parent = workspace
-- later in the game
part:Destroy()
This destroys unused objechts

** You are now Level 3! **

[final dove]

local connection = part.Touched:Connect(function(hit)
print("Something touched me")
end)

-- later
connection:Disconnect()

It disconnects event listeners

table.remove(myTable, index)
This cleans up table

while true do
task.wait(1)
print("Still running safely")
end
And this controls loops

I hope this will help you
