Yes I did it. It's just that is seems they have just this one/very few examples only. And none of them are 2D stuff.
iirc, Unity doesn't have a dedicated 2D Library, (or didn't last time i checked) you have to use the GUI side of it if you wish to use it for 2D.
You can also set a camera to use orthographic projection + there are some 2D libraries / plugins in the asset store.
Allthough for a 2D game there might be far more suitable engines than Unity out there.
