I'd love for there to be some way to start experimenting with it. I understand it still has a long ways to go, but I'd like to get more of a feel for it outside of Jonathan Blow's 4 hour+ work sessions on Youtube.

I understand the likely reason why he isn't, because he doesn't want to have people bugging him for support on it, but if I could sign a "I promise not to email you any questions about it and I'm using this at my own risk, pinky swear" and get access to download the latest version of it, I would.
