So, good news! I had a two week vacation scheduled, but due to unforeseen circumstances my gf had to work and I was left home alone for two weeks with nothing to do. So I spent 14 hours a day writing, coding and creating the artwork. I was in a groove and had a lot of inspiration of where the story needs to go, so I hit the ground running.
I'm happy to say that Chapter 2 (containing the ending of day 2 after the cliffhanger, plus day 3 and 4) should be all finished within a week I hope. I'm aiming at end of next week. I will then have written about 3500 lines of Ren'Py code which must be a world record somewhere. Chapter 1 contained about 1250 lines, so chapter 2 will almost be 3 times as big. Keep an eye out!
