Played the demo, will buy this game in the future.
I really like the visuals, the exploration and the story. The environments look great and well detailed, the atmosphere is done well, mysterious and haunting.
I found the shooting a little disorienting given the fixed camera angle, I'm sure I'd get used to if I played more, it's manageable, but the first impressions were not the best.
Overall though, i think it's really good, give it a try.
