Good game, but YOU WILL need a walkthrough
First off i absolutely hate when an adventure game is so hard at times that it forces you to open a walkthrough, the feeling of accomplishment and the suspension of disbelief goes right out the window. It's the difference between a decent adventure game and a great one.
Was there a clue anywhere in the game that the password to the computer was "satan"? If so I stand corrected, but moments like that in a game where you need to enter something and you're not sure if it's a puzzle or just dumb luck guesswork really kills the fun factor.
