Don't wanna upset you buddy but 90% of devs in this business are just like this guy, can show you some example:

I could keep writing you other cases for hours... they are all the same, deal with it
Can't really agree there.
The dev here has delivered 1-2 interactive scenes in revolutionary quality, even more amazing that he is doing his artwork with a mouse (unless that's some bizarre nerdy humor to write that in his profile).
The writing is completely different to just about any other game, in a unique style. The scenes with the sis/mom feel realistic, voyeuristic, tabooful like you're actually committing a crime. Players coming back for more. Despite or because of the stylized and simple artstyle?
Problem is just - well, read the thread backwards. It's been abundantly listed in all details.
The progress over the years was too slow, even seemingly going backwards or in circles since around update 0.2.7.
Not really going to explicitly comment on the games you mentioned (because it's OT and against enforced site rules), but two of them are among the most prominent and most successful scams in adult game history, while the other one is just a mega-trashy NTR slop game i wouldn't even list at the bottom of the top 100 adult games.
