The dev was quite active at the start but got bombarded by people complaining about the NTR part. I think that contributed to why the dev got demotivated. So yeah may be not "scared" but seemed to have been a sticking point.
I don't believe that the developer got demotivated, because of NTR (or whatever it is called now) - there are plenty of games with NTR tag and nobody cares.
Here is one of the laws in this life (that
I've learned personally):
if you want money - you need to work.
My advice to
VIGOR GAMES (unless it is really a health issue) -
continue working on this game or
do something else with your programming skills (like a real IT job).
People are not going to pay just for promises (and a few screenshots) because "talk is cheap".
You have a good game here (many people like it) and if you cannot (or don't want) continue working on it (which I personally think could be a gold mine) - just do something else in this life (in other words, game development is probably not your thing).
Peace.
