I don’t agree. It might be hard to believe, but there are people who don’t want to play NTR games where sex happens too fast and without proper context/buildup.
Another thing - are you supporting the game financially or just offering criticism for free? Because as an indie developer myself, I can tell you money helps keep projects alive.
If you don’t or can’t support it financially at least be thankful someone gave you a free game. There’s nothing worse than working on a game for 12-16 hours a day and then coming to a forum seeing “fans” tear you apart or start demanding things while offering nothing in return - again, money is very welcome.
In the end, if you know how to develop a better game, what’s stoping you from making one?
