Maybe I'm reading something into how you're wording stuff here but you seem kind of annoyed and I don't understand why. This isn't a complaint or allegation against the developer. People just want to know if there are intended relationships and the game presents a hierarchy. Nobody is calling foul or claiming the game is bad because of needing a little clarification, it's really no more than a minor inconvenience.
Maybe you've missed some flavour text, or maybe it's the broken English, but the MC does threaten to tell Moira about Victoria smoking to get her to remove her clothing. There are other instances of Moira behaving motherly such as rewarding you with an allowance for completing household chores or gently scolding everyone for talking at meal times. Like I said before, her role could be veiled as being the landlord or as the head of the household in some other way. But that relationship hierarchy is there.
Again, this is not a slight towards the developers. This is about answering someone's question when they asked about any possible intended relationships that might have the dialogue make the most sense.
And yes, people can put whatever they like in there and just run with it by all means. I play some pretty weird games since the Patreon rules changed because I don't bother applying incest patches. I personally am not as bothered by the idea of relationships between landlords, tenants, and friends having to be strangely a secret because "no one will understand" etc. But someone asked in this case and I don't see why answering them might be bothersome.
You misrepresent your opinion as "FACT"
The confusion with the intended relationships comes with the fact that the intended mom character doesn't have the typical milfy appearance
I explained that you have no idea what the developer's intention was, and that you were speculating.
The player can say that all the game characters are "Mom" if they choose to. The developer intentionally left it open so the player can fill in the blank.
The fact that your mom is a whore, is irrelevant, and not the intent of the developer, you fill in the blank however you want. Mom, Sis, Dog, Faggot, Cat, Muffin, Bunny, Pet... there is no intended relationship, IN FACT the developer's default is "friend".
Your false statement as to the developer's intent. Is an attack on their moral character.
