I don't want to sound rude but... You know that the point of an Early Access is for developers to receive feedbacks from players and improve the game according to the feedbacks ?

They released the game before it was finished
because they need feedback from us, also I've never said in my post anything about the mechanics that we know are going to be in the final release. When I'm asking "why X mechanic isn't in the game", it's because the dev never talked about including it in the future (so I'm just remembering them that it would be cool if they added this mechanic to the game).
If we want the final release to be even better, all of us need to criticize the content of the Early Access (in a constructive way that allow them to improve it, not insulting them of making a childish tantrum, devs should just ignore these ones) and help the devs.
