Thank you for creating and uploading a video! That's amazing. It's really useful for me to see other people play the game like you did. Of course it's frustrating for me to see how hard it is to figure out that clicking on the portrait does something, but because of playthroughs like yours I was able to learn that. Hopefully I'll get it right next time!
Those bugs were about 15 minutes to fix after the jam. Too bad I didn't find them in time.
As for the books feeling samey, yeah the content in there didn't get enough love. More biomes, more differences between the maps, this would help a lot. As for mid book saves, well, let's just say you don't want to deal with the bugs my save system has when you're not yourself on a map that was modified by procedural generation changes. Saving in the library? Mostly rock solid. Saving in the book? Explodes! :)
