Yeah, sure.
Unfortunately it's actually really difficult to quantify how much I've done and how much there is left, due to a variety of reasons, but I can give a rough idea. I'm actually approaching the end part of chapter 5, which is the last chapter of the game. That doesn't mean I'm close to done, though. There's one more gigantic file that contains almost all of the scenes (~7k lines) that I still need to do, as well as do a pass-over on some things and to do some extra work to make the game suitable for playing. Also keep in mind that my pace will vary heavily from day to day depending on real life. Basically, it'll be done when it's done. Hopefully soon. Within next two months at latest.
