Thanks for playing. I'm glad yo enjoyed it (otherwise I imagine you wouldn't have finished it.)
Book 2 is only a thought in my head. I have the basic plot done, but I haven't started drawing pics, designing puzzles, or any of that stuff. Honestly when my son was born a year ago, I decided to "finish" BA (that is make the first book playable) just so countless hours of my life wouldn't have nothing to show for itself.
I started making the game 8 years ago when I was a) single, b) underemployed, and therefore c) with lots of free time. Now I have a wife, son, and job, time-consuming tasks like making BA:book 2 are really far-fetched.
It would probably only happen if I assembled a team, where I would be the story director...but that would involve finding talented and motivated people to devote countless hours to a project for no $$.
Anyway, I have been thinking of doing a walkthrough, since I have heard more than one request for one by now. So, when I find the time, I will likely put one together.

In the meantime, you can play one of my other (admittedly worse) games.
