How many chapters? (Patreon)

As you may know, each new chapter has a new version number (0.6, 0.7, etc), but now that we are approaching the number 1.0 I was thinking that this numeration could be a bit confusing, since it could be understood that 1.0 means that it's a final version. 

I think I'm going to need a little more than 10 chapters to tell this story, and that's why from the next release we'll call the versions only by chapter number.

And here comes my question : Considering the way and speed in which this story is developing, how many chapters do you think would be an ideal number for this game?
