Most developers do not charge full price for a game in early access. It seems that all of the positive reviews on Steam are from Larian fanboys. Reading deeper, even Larian's "finished" games are broken in many of the same ways. I am glad that I am under the play time to refund the game.
To be honest, refunding the game is probably a good idea in your case. If you cannot grasp what Early Access means or cannot be bothered to read the Steam page (and also judging from your last post), you would hardly be able to provide useful feedback.
