Hello Hamster,
news about the development are frequently shared with the community. However, this happens via this forum and the homepage… not via Kickstarter. So far the Beta is not out yet. The devs are still planning to start it in December, as it was initially planned. Probably the release will be handled by Humble Bundle. Just some time prior the Beta starts, Radiant will share the eMail-adresses of all backers with Humble Bundle, who will send out a code which you can use to download the Beta. So we will have to wait a bit more, prior receiving any post from the devs on that one.
If you cannot wait, just take a look into this thread from one of the moderators. You will find a long list of details which have been shared in the last weeks…
P.S. The next piece of information can be expected tomorrow… Desktop Tuesday.
