This early access is more like Q&A session on their game, they tried to fixed it by small amount and then they released even more bugs to make their game became harder to play.
This kind of practice will result in short-lived game and eventually devs do not care anymore and just keep saying "we will update soon" but months and years passed, they already gone with player's money.
I already seen a lot of games just come and gone in few months or stay in there but nobody tried to fixed/update it while it runs automatically until shutdown notice happened.
