Side question first:
I noticed that the mythruna pre-alpha download under
http://mythruna.com/download-now/ is marked 20120627 which by my brain say that the last update was on 27-06-2012
Have there been any releases since then?
(As I'm new to the community I'm a bit confused by it, and may have missed something)
Yes you are correct with the date, June 27 2012, was the last time there was a public release. I believe not too long ago there was a Donator test update, but Paul (the creator) is working on physics, world creation, new menus, ect., that takes quite a while, and he is the only one working on it so yea
you can see some of his update videos at
