I don't know where to begin. This is a massive step backwards. It took me ~2.5 minutes to even figure out where the documentation was, and I am quite used to navigating the bowels of strange sites, often in languages I cannot read and most of which google translate cannot fully translate on the page. That is a MASSIVE problem when the website is about a library for a programming language.
Your scrolling is utterly insane, and the layout is horribly scattered in seemingly random clusters. It's a giant, confusing mess. I felt like I was going cross-eyed trying to figure out what was where.
I respect the wish to try to take new approaches, as I myself do so quite frequently, but this is not a good approach. I cannot see any scenario (other than perhaps mobile, which to be fair I have never been in this area and therefore have no knowledge, and honestly I don't see a scenario where someone is coding a game from mobile) where this website would work.
I apologize if this seems abrasive, I am merely trying to offer my own criticism.
