BRIAN! My brain hurts, but I (finally) got the PC unlocked... after 2ish hours.
This was an amazing demo - incredibly put-together, clean character models, unsettlingly silent atmosphere; the list goes on and on. This has more character, plot and detail than 'full' games that charge $3-8. Best of luck on the rest of the development.
Bottom line: I CAN'T WAIT TO SEE WHERE THIS GOES! :D
