It's cool, but I actually find it pretty bad as a website. The UX for navigating and all that, it's bad. I was hoping for some innovation in UX which justifies the use of 3D in the website.
But my point is that, it's not bringing in a new paradigm of UX that you'd want to immitate.
Though maybe it could if others started making "video games but it's just navigating through a website as you play".
As a portfolio to demonstrate your three.js skills for web game making it's really good.
