I'm already planning to introduce more choices in the future. Just right now I think it is too early in some plots to see an actual impact in them and in the main story. Also I'm a bit limited right now with what I can do and introduce in the story, mainly because I'd need to have more sprites and other graphic material if I want to have more "routes". But don't worry, this story will have more choices, and with the help of the supporters I'll be able to get the graphic material I'll need.
You just wait when we get to CHAPTER 2 and CHAPTER THREE ;)
