In the game you can stop NTR from the third chapter as it says. and I think, for what? Once you reach that point the non-ntr players would have already left. At that point it doesn't matter if the NTR can be stopped or not. If you really think that this can attract non-NTR players, you don't know what environment you're in.
By having that option to stop ntr at that point I think the story took a hit. I think the dev should have kept his original vision, because if you only play one route which I think most people do either because of time and/or preference, you always feel like you're playing half of the game.
As for my opinion on the game (first time playing), couple of complains that I have on the visual side, the mother look way too young, she could be your sister, just because she has a bigger boobs and slightly taller doesn't make her look older. My other complain on the visual side is a minor one, it is the fact that the mc uses a thong to swim, sure that could be the lack of asset, but whatever it is, it's not a pretty sight, please, don't show his back when he's swimming
.
As for the story, what I dislike is down to my personal preference, so most of you probably won't agree with me, but I think the pace is too fast, the ntr pace is actually well done and I really like what I've seen, its just that the pace involving the mc has no buildup, in a instant your sister jumps on you, suck your cock and have sex before you even seen her naked or kiss or whatever else, the same with your aunt to "test" you for your cousin, zero buildup.
Overall it may look that I hated the game based on those complains, but I actually like it and I'm seriously considering on supporting.
