Two things I liked: your actions have logical consequences (at least for me) and the story does have some twists. Actually, make it three: the action and combat resolution systems work well to keep the game moving.
Two things I didn't like: the PDF could have hyperlinks to aid navigating across paragraphs and maps (I bet many people will play this on a computer or tablet instead of printing the book) and some character options don't seem to matter so much as others (but I didn't explore every possible path in the book.)
It's hard to comment much more without spoiling the game, so I'll stop here. As with most paragraph-based games, the replay value isn't very high although I'll probably try again with different character choices.
