Hello :) The preview characters are main what I add in the mini monthly updates on my patreon (you can just copy and paste your save file from a previous version), Chapter 2 will include all the seduces I make from now until it's release (some preview characters i know that I'm saving until chapter 3/4). When I release Chapter 2 it will be with Chapter 1 within it, they won't be separate games (I will figure out how I can sell Chapter 2 at a reduced price for people who bought Chapter 1 on itch)
