It’s a good point and I do intend to overhaul the sales demos to make them more variable and replayable.I don't have an issue with Dumb Bitch's difficulty and stat losses on failure, just the lack of variation and flexibility of that demo compared to later ones. And visually speaking this is the hottest scene in the whole game for me.
If I had to guess, I'd say the Dumb Bitch demo must be among the very first to be developed. For example, later demos and scenes use bars to represent orgasm progression, where Dumb Bitch uses a simple "X / 15" format.
I guess I just wish the older stuff was elevated to the level of quality and consistency of the later stuff.
Your assessment is correct that it is due to this being a much earlier one and now if I revise the demo I can bring some of my latest learnings to improve the scene.
