It's released in this state because it isn't finished. It will annoy some people - I've seen it happen with other Early Access games - but I don't think it's something the developers should be worrying about. It's not their fault if there are people who will buy an Early Access game and complain when it isn't, or doesn't feel finished. It's par for the course when the game is still being developed and people who want or expect a finished game should wait until it leaves Early Access.
