Strange things are going on: Some minutes ago I downloaded the game, now it isn't possible to download it again and all I get if I click on the button is the demo and the soundtrack. I'm a backer.
edit: aaand now it's here again. Quite peculiar.
edit2: I think something is wrong: The game is now downloadable (the full version) even if you don't buy it. It's right on the main page together with the demo.
