No I think the beta is already out, they're just testing it themselves and with their loyal subscribers. The reason why I thought of this is because I took another look at the membership levels and it said that each games updates are tested by the beta-testers. It would explain why they suddenly went dark after fixing almost all of the bugs (That's the positive thinking). (The negative thinking) the other possible reason is that they are just scammers, trying to extend more time just to get more members and money.
Nope, in the past, beta was early release for 25$ Patrons. After three days he would release it for 10$. As soon as beta was released, it would get here... maybe after 30 minutes at best.
Now it sounds unbelievable, but this game actually had solid release cycle. In 2018, there were five releases, and Special. In 2019, he got "problems with depression", and we got 0.6 in late of October, bugfix in December. Then 0.71 came in 2021. Anyway, I don't think he will release anything, but if game actually gets to beta stage, it will be here in no time.
