I agree with David--the game has some nice touches and an old-school feel, but the fact that you can't actually complete it really ruins the fun and leaves the player hanging. I too reached the 58 of 68 point and can't access the final component to proceed. Also, the appearance of items in previously explored areas is frustrating, since they are seemingly unrelated to any action. An item will just appear in another part of the mansion after completing a task in another room. Even with walkthrough help the game can't be finished.
