I enjoyed it back in the day but it's a different era's game. You have to enjoy throwing yourself against a brick wall for a very long time until you finally crash through the door, and possibly taking notes and making diagrams or maps as you go.
I remember it being lush graphically, for the time, and very satisfying for the puzzles I did crack but I gave up before finishing it. I think it was some kind of blind maze that finally did it.
