One post jam comment, I feel like your ranking is really harsh, you were for me one of the best entry in this jam.
My guess is that having a lot of reading may not be the most suited mechanic in a Jam since people want to iterate fast between games and may discourage people to discover more of your game (even if the story is super cool, like yours, and your reading system by holding pages was not boring). Also, maybe people missed the hint option ?
Anyway, keep the good work for your next projects :)
