I replied to another comment with the three words needed to actually escape if you want to look that up. What spells have you found and what, if anything, comes through as the word's meanings? I'm working on clarifying how to broadcast to the player what the words mean, so feedback would be helpful here.
The save option vanishing should be fixed in the latest version (1.06), so that should help. Additionally, once you've read the book a few times, you'll be able to get more information about what the words do. Hopefully that helps alleviate some of the frustration, but please let me know if you still have trouble and I'll work on a few other things to help out.
