This is a game that does get one involved. Puzzles are in general easy to medium hard and the writing is engrossing. But the end left me greatly annoyed. Apparently I was supposed to find something halfway through the game (I finally broke down and read the solution to find out what I had missed). But in the beginning I looked and it wasn't there and near the end I looked again and it wasn't there. Apparently only if you looked at a particular time did the required object show up. So I fought my way through to the end only to be completely stopped.
This is a long game and I'll damned if I am going to go back and repeat half the steps again. So I never finished and that's a shame.
