I mean, you're entitled to your opinion.
Go ahead and believe that trite nonsense.
But that opinion means less than nothing to me, so there's that.
tbf if the game hasn't got what the guys looking for and it's a game that costs money then why would he get it?
Also the devs seem unprofessional when it comes to dealing with such people.
If you're gonna charge people for the game then you're setting yourself to a much higher standard and must be viewed and judged based on the higher standard.
It'd be a different story if it was free
Never said there was anything wrong with your game or what you like or don't like, so you don't like harems, that's fair.
But you're gonna get all sorts of people like this requesting what they want and the best thing to do is simply just ignore it instead of taking it personal. That guy will leave, he's not your problem anymore but replying to him saying you don't like what he does like creates conflict and no one wants that and also potentially alienates other customers or fans that may be into that too thus turning them away.
Basically be more professional about it and don't get personal.
Hope your game succeeds and you get plenty of success <3
