Thanks!
As for what all of that stuff is, it is in some way tied to the forces behind Silverstone. After the good ending, pretty much everything is back to "normal" in a sense. Walt isn't psychotic, it's Silverstone's influence affecting him. Wish I could go into more, but it's hard to get into without getting into the main meat of the full VN taking place in the town. All in time :)
And thanks for reading the about, as well! Trying to rest, but it's hard taking breaks as a workaholic lol
