Err, the state of this game is kinda told to you multiple times before purchasing. It isn't hidden or anything, you were an informed consumer putting your money to a title that has openly admitted to being broken and unfinished because it is an early access. You agreed to buy and play a broken game, thereby (assumedly) bypassing the policy that lets you return broken games, especially because this is not considered a full release or anything close. This is closer to a kickstarter where we get a demo at every update and get to test some things, while Larian holds onto a ton of things themselves. Rather, this game is basically a preorder with the bonus of a glitchy demo. When the game officially releases and it is "broken" it is possible you may be able to raise your concerns with steam, but as it stands you got exactly what you paid for.
