I bought the game today. Wonderful! I studied it with the demo and I hope to find the time in the next days to play it as much as I would like.
Unfortunately, I'm very busy with music, blogging, social, but you don't need to complete the game to feel the atmosphere, the depth and the passion the developers put into it. Considering I'm in the Industry since 2002, and I love role play games since AD&D first edition, I hope you'll appreciate this. So, THUMBS UP!
Also, I highly support independent developers. I think you are the ones that can really give innovation and depth in the videogames industry.
N.B.: I've noticed problems with Windows 7 in two different systems I've got, whatever directory you choose, also the default one. I solved in both situations running the game as Administrator. This is a solution you suggest for Windows Vista, but you should add Windows 7 to the suggestion.
