JasonB is right, the game is very buggy and only playable to certain parts right now. Should really be alpha, but there's gotta be a cash grab right? This is going to be a really good game though and the devs are very actively bug fixing and adding content. It's already had 2 patches since this came out and scheduled for another very soon. I may have to just buy this damn thing to play it. Bah. I'll wait....
