It looks pretty good, although I admit that some things look a little weird to me. Still, it's cool to see how they do this stuff.

As I mentioned already, Nintendo has a knack for shutting these projects down late in development.

It was the first thing I thought of when I saw the video haha, the reputation Nintendo has for suing or shutting down almost anything related to them. Hopefully nothing happens to the guy, although by not distributing it in any way, I think he's protecting himself well from Nintendo.
