Sorry! The game isn't abandoned, my life has just been crazy busy lately. Plus, I made chapter 4 too big, so it's taking longer than I originally hoped.
Sorry, I thought I replied to this at the time, but I did see your post and changed the tag. Totally my bad! I didn't notice that the tag was clicked, so I really appreciate you pointing that out for me.
Since my progress hasn't gone nearly as smoothly with this chapter as I'd hoped, I decided to release Chapter 4 in two halves. I'm hoping to have the first half of chapter 4 out in December. It's still a soft estimate, but I'm hopeful!
