I'm glad you enjoyed the game, to your bug related issues when you opened the book I'm not sure why you could not walk, also the fatal error you can carry on playing and ignore the error the game will still carry on. If you would like me to play a walkthrough of the game and upload it on to YouTube so you can see how the entire game plays out I'm more than happy to.
Ahhh, I would have loved to play it myself, but if you could show me the PLAY THROUGH, I would like to see it!
A friend of mine played it himself after watching my streaming, and he got a Fatal error in the place before tram.
