i'm not sure if i was just unlucky but i couldn't get to any kind of ending regardless of my choices :( at some point i'd just get completely stuck
but i really like the idea of being able to shape the narrative by deciding which book to sell to these people coming to your store! and i also really liked the breathing effect on character portraits and how their emotions are represented. made them feel really lively and non-static compared to how visual novel type games are normally :)
