Im pretty disapointed in you. As an inde-dev, NSFW or not, you still need to eat. This here is a harsh market and 2.80€ for a second game isnt much to ask. Half of the consumers wouldnt even have noticed if it would a dlc for 2.80€. I am pretty sure this dev is payed way under the minimum wage and might be strugglying to keep afloat. And what about the devs that just strait up leave in hard times? This one here wanted to deliver what most of you wanted but couldnt do it for free.
Tho, I still need to agree that it is disappointing and can understand if you feel betrayed. But you cant rly call it dishonest if the dev litterly tells you the reasons the old game is discontinued.
Anyway, thats just my take, as a dev as well.
