I don't have enough time to be a tester for you,
Messieurs, but I will let you know of one general issue I'm seeing that should hopefully be pretty easy to correct. There are some places — like where the MC hides in the headmistress' office — where the text doesn't match the render for several sentences. There are at least 6 clicks in this specific example where you already see the nude render before the description even mentions that she removes her clothing. Hopefully it will be simple enough to modify when the render shows to remove the delay of the text catching up to it.
Also, as a side note, there are a couple of places in that same Karen scene where, instead of something like this:
Karen
Yurrrrhaawhhh!
the text box shows this:
Karen — Yurrrrhaawhhh!
I assume it's supposed to be Karen making noises out loud (and so displayed the first way), since the scene is from the MC's perspective. Also, you have a couple of instances where things
are displayed in the first way, so I would guess the italicized text with Karen's name is a formatting mistake. Anyway, I just thought you might want to know, if you weren't already aware.
