do you prefer hourly updates on the status of the next chapter, or actual development work on the next chapter? this appears to be a 1 person operation, and digi_b, so far, has turned out a pretty high quality product, with regard to story. i'll take well conceived storyline over frequent updates, any day. even if there are 2 or 3 people, behind the scenes, helping develop it all. some devs like to talk a lot about what they are doing. digi_b sees to prefer doing it and doing it well.
have you played beyond chapter 1? or are you talking about through chapter 4, when you say "demo"? the first part is good, no doubt. but this story actually gets better as you progress. and for chapter 5 to get better than 4, it's going to take some work, so it's going to take time.
