Alright so this game is definitely an ntr game. Even if tara took 100's of dicks during her travels, there is no need to even mention or hint towards that fact, but what's worse is that after you introduce the main character and give the player control, you immediately have Tara fuck a random dude/ntr you and see it happen (you could play it off as a fake out, but you just confirmed that isn't the case at all yourself).
NTR is a very specific genre that consist in: You are a guy in a stable, commited and monogamous sexoaffective relationship of some kind with a woman, then another guy messes with that, seduces/forces/blackmail/whatever the woman you love and love you back, and eventually, she falls completelly for that guy because no matter how gross or disgusting the guy is, he fucks so well that suddenly she doesn't give a fuck about all those romantic, deep feelings she supposedly had for you. She also forgets that you have a dick capable of fucking her too and circumvent the fact that if you want to fuck the brains out of a girl, you usually will be more successful if you properly eat her pussy rather than actually use your penis. If you ask me, it feels kinda silly and boring for a fetish, but hey, I guess all fetishes seem boring and stupid at some level if you are not fond of them. Anyways, that's the core of it. That's Netorare for you all.
Now, from the game story perspective: You are the main character who did just arrive to that small town, after years with no contact with your aunt. But all the characters in town, they were not floating in a void till you arrived. Did Tara fucked a random dude? Or did she just fucked a guy she knows whose relationship is unknown to you because you are the new guy in town and know nothing, didn't even kept in contact, on top of that you are her nephew AND to her at that moment YOU are the sexually irrelevant one?
That's the problem with you guys. And no, the problem is not that you want every female character with a portrait, potential sex-interest or not, to be your (vessel character) absolute property from the moment you lay your eyes first time they are presented in game (Though it may be a problem
for you if that mentallity reflects on your real life, but that doesn't concerns me). The problem, again is that you claim all that not fall into that category to be NTR and frankly, you don't know shit/don't give a fuck about what NTR actually is. So, while it's ok you disliking any game in which you do not imperson the only relevant male in sexual terms and whose dick is the center of the game universe, you can become just a little annoying claiming bullshit again, and again, and again and accusing the devs to be lying. It mildly annoys me just by reading, I wouldn't want to imagine if I were the dev.
And for the game... definitely seems interesting, it has gorgeous art, and I see there's an effort to make it stand out from the average RPGM games with default tilesets and sprites. Obviously the devs have a clear concept of what they want to do with their game. I wish them well, and to not let the whinning undermine the game they actually wanna make.
