Thank you for the feedback. I can tell your calculations are off a bit because it didn't take me as long to create the rest of the game, so why should I take 4 years for this chapter? I can understand the confusion. You see, while I have started this chapter, I also added three different endings to the wrestling match (Nathan, Ned, or Ron can rescue you), two other meetings with the headmaster (you can either go with Julian to the headmaster's office or go with Ron to his house, both with one additional ending (with Ron in the Park or with Julian at the milking station in the basement), plus a rework of the relationship mechanic with the headmaster including alterations of the first encounters with him. Then you have the chapter where you can choose your outfit. All of that before you even enter the spa day. Also, there have been releases for BEngel, and I made a whole new game demo for "Heartless Corporation.
You see, progress is only sometimes made at the end of the game. You could try replaying the game if you haven't done so before. I am sure you'll find some new content.
