Too much and not enough
You had me paying attention (and enjoying) until it came time to gather notes. Here, the game began to falter. Although it only truly fell apart once the need for the password on the computer arose.
After consulting a video walk-through, I was informed what the password was, but could not for the life of me discern how that would have been possible to figure out without an outside source. And the game completely falls flat with the ritual segment. Once again, consulting a walk-through, it showed me how to "finish" it. However, even that combination did not work, so I am led to believe that it is merely some random trial-and-error until finally the games gives you a completion or you close the window in frustration.
The puzzles should be challenging, not impossible, and should not require more effort that what would be expected of a point-and-click game. If the game presents a challenge equivalent to an SAT test, or breaking the human genome, far too many people will become disinterested and walk away.
Good concept, but the further into the game you get, the less motivation to finish it thanks to the increasing complexity of the puzzles (without the proper means to problem-solve for the answers).
