Sorry, been busy lately and just getting back to this thread....
With the dialogue remember there are two paths but they are actually sort of close, the difference comes on how Peter (the MC) does the corruption. This is revealed in all the dialogue, and is fairly consistent overall.
- Purity - is more about them internally convincing themselves that what they do with Peter (the MC) is fine, and its all done out of love/lust where giving in to the situations is just normal
- Corruption - is more of an external influence where Peter (the MC) blackmails/forces them into the situations to where they eventually just give in
The grandma stuff looks cool, but even with Corruption the scenes take time for the characters to give in, speeding up anything just for the sake of scenes will make any new characters feel rushed overall.
Very much this. The point of the game isn't just having a ton of scenes, but the stories that lead to those scenes and that build up the erotic context of it. Spacing the progression out a bit is just proper design.
With that in mind, I have a suggestion - just a suggestion, as always - regarding scene progression.
If grandma is going to move into a house behind the player, why not alter the masturbation scene for her? I know Mrs. Amos already uses it, literally next door, but it would mean that at night the player could choose to either look into Amos' window or grandma's window. You could also have him take a picture of her, if that's at all relevant.
This would of course occur after grandma first visits the family and moves in next door. Before this the player doesn't get any sexual vibes off grandma, but seeing her masturbate reveals that she has a still-active libido, which gets the MC going, as it were.
This could lead into the MC doing chore (like the garbage disposal one) for grandma to earn point, with an option to either say something sweet or flirty each time or something like that.
The second scene I suggest is Kimberly's kissing scene. My idea would be to have grandma tell her grandson that he'll make a pretty girl very happy someday with all this hard work. After a certain purity/corruption threshold, the MC has the option to confide in grandma that he doesn't know if any girl will like him, since he doesn't know how to properly kiss yet (probably a lie). This leads into a redone version of Kimberly's(?) kissing scene as grandma eventually gives in and decides to "teach" the MC how to do it.
The pure version could be the MC saying that he thought grandma could help him since she's always so nice and she was married for so many years or something - and the corrupt version could be him "accusing" (lightly) grandma of not wanting to help him with his problem when he always does chores for her (or something like that).
Just my two cents.
