The beginning of the game (the webpages) is such a great emulation of navigating Web 1.0 sites on old CRT monitors that it deserves mention on its own- way to take me back!
As for the gameplay...damn. You really nailed the building tension; between every sequence at the computer I was on tenterhooks. The atmosphere is impeccable and served well to wind me up for that ending. I'll be thinking about this game for a minute. Excellent work!!
