Thank you so much for your response. I believe you misunderstood me and I apologize if I was unclear.
Without spoiling anything, I got the feeling that Superlatives: Aetherfall is intended to be (or written with the potential to be) a multi-book series with the storyline continuing ala Hero Rises or the Vs series. The save system I was referring to was the ability to save how you ended the book so that it could be imported into the next in the series, if that book is ever contracted and written.
Thank your for your response.
