*Spoiler*
What a great concept for a game! I can't believe you did this in such a short space of time. The stories had a really nice feel (like parables), which worked really well with the art and the atmosphere. Wonderful music too. One thing I would say - the part in which the mother decides to throw her baby away felt a bit like a dark comedy compared with the others (not sure this was your intention - I also appreciate how difficult it is to perfect stories during a jam - I certainly struggle with this).
I really do hope you expand on this. It's such a wonderful idea. Like a story-puzzle. If you do, I imagine the stories may be bigger, in which case, perhaps a journal/quest system might be useful for the player. And an easier way to dip in and out of each story. I did find it a little difficult to remember which book was which story and also to plan out how I wanted to fix the story.
Really fantastic job on this beautiful game! Well done.
