Okay, I've been through the code (phew!) and I think these are the conditions to get each of Deb's gallery scenes. There might be some things I've missed because it is kinda complicated.
Hiding the details because there are a lot of Spoilers
Thanks for taking your time to do that man! I see two of the scenes are for manly style players, and the rest are just variations of the scenes I did unlock. That's good to know.
Those are just different variations of the same scenes. Chapter 4 scenes are if the MC was spanked or had the thigh job. Chapter 5 are if he was caged or not.
It's a bit confusing as is, I probably need to do something about that. In chapter 6, I just made one replay icon and then the player can choose which variation to watch when the replay starts, even if they didn't see all the options. Maybe that's the way to go.
I see, now I get it. Yes, Chapter 6's way seems to be the best to avoid confusion imo.
Btw, I'd like to take the chance to thank and congratulate you for the game. Unlike most adult games, it's characters are well written and the scenarios are realistic.
Also, as a psychology student, I find the topic of MC's research proposal about the origin of fetishes really interesting. I found myself enjoying his conversation with Bri on the subject a lot. I happen to have a similar opinion. That, just as sexual orientation, fetishes are something we're mostly born with. Or at the very least, we're born with a strong disposition towards developing them, if the necessary minimal environmental cues happen to enable that development.
Trying to explain it through childhood experiences just sounds coherent, so it's easy to believe. That's how our consciousness works, looking for the most coherent narrative to explain things. But imo, that's just the trigger for something that was already there. Thousands other people could have that same childhood experience and not develop that fetish because they lacked the predisposition for it.
Anyways, I don't know how interested you actually are in these things, but I'm just glad to see topics like these brought up in these kind of games. Thinking about why we are who we are is always fascinating.
