I started playing yesterday lol. I understand why its selling like hotcake. But I wish I liked it more... All the animations make it feel like a very expensive game so its a bargain for that price. But at the same time it has no soul. Too many men after the heroine for how superficial writing is. Relationship with the hero is also superficial. To me the NTR/BSS separation isnt always very important. I dont care about the name of the relationship as long as it feels like the feelings are there from both characters. But games like this have no chemistry even with the flashbacks. Plot also is superficial and uses device that cheapen the NTR without hot payoff (unlike Takeda game). Its a very forgettable game with great art and animations. Fap and forget lol.
To me a NTR game can be great because of the writing alone. And at the same time you can have basic writing (as long as its not actually bad) and make a great game with the presentation of NTR. Like mystery mechanics and stuff like that. Obvious examples would be all the good NTR games with 3D Koikatsu graphics. Or that アヒルLOVE game which btw Im pretty sure has public demo for your second post. Obviously everyones happier if it has both good writing and mechanics. But good art alone cant make a good NTR game. The presentation is a lot more important to me. And NTR騎士 is pretty boring about it.
