Hello!
Unfortunately, I can't leave Mr. Bob dead (at least for now) because he's the driving force behind the plot. But I really like your suggestion about other families!
Although I initially wanted the good ending to be open, I've determined that the knock at the door was actually Jack who was checking up on Alesa to see if everything was okay. And there's a reason why: I'm already working on a sequel, where Alesa will get real closure and I'll tie up loose ends.
Thank you so much for playing and your feedback!
