Complex

I have a serious question: I just donated 10$ to the game developers. Thus, I should have access to the latest version of the game at all time. Indeed, I was given a link to download the non-demo version of the game, which I just downloaded. BUT -> The content of the game is exactly the same as for the demo version! And I have absolutely no clue, what kind of building parts are shown in the video above, because i have (almost) none of them ... Whats going on?
