A simple program for Test.

Asset Count : prefab Count.
GameObject Count : Instantiated Count.
Add Button : Add 100000 cubes to Scene.
Del Button : Remove all cubes.

Is it normal? that big memory does not return to OS.

I use this API for remove Cube.
GameObject.Destroy() : for Instanciated GameObject.
Resorces.UnloadUnusedAsset() : for loaded asset by Resources.Load()

And I call GC.Collect() right timing.

What’s wrong with it?
