Hey ! I've only stumbled recently on this game but I loved it instantly ! The universe is really cool, I love all the cast and I could tell you are really invested in your game, it's really a little gem !
Anyway, just wanted to say, love it, love your work, sending you lots of love !
(oh, and to answer the actual post, yeah, the pricing of a ""premium"" double NSFW version does sound fair, you definitely deserve to earn some kind of money with that, especially with the amount of work and passion you put in !)
xoxo!
