I set the price of the work (this price is from 2018, I was ready to move the history for money then, but wanting was not). Now the exchange rate is unstable, but in my currency, for a full port 30000 rubles. At the current exchange rate it is $376.
Spent a lot of time, and also made a mod with Eric (I'm talking about the one that is now, no another new, because the first goal - a full port) on the order of the first customer.
There has been a lot of disappointment with BB game remakes, and I at least am tired of being burned by them. On my end though, if I see NTR plot go forward, and that it seems legit, I would sub to keep development going.
You're the only dev even talking about NTR, so I think you have a good niche group there if you give it a chance beyond the port. Might not be instant for a lot though, some may want to see a patch or two post port before jumping on board.
