So good! It’s a fascinating idea that we haven’t seen before, and pulled off with a great snappy interface.
Sadly, I played twice and both times got stuck. The first time, somebody asked for book 39A, and there was no such book (I checked every shelf in the 30s and 40s). Second time, somebody returned a book, I put it in the proper place, and they didn’t leave. Maybe I missed something?
But hey, bugs or not, this is one of the best games here, easily!
