It's not exactly ntr. There will be Amber-Henry scenes for example if you choose to give him advices and leave Amber alone from the start. So technically it's not ntr since she's not your gf but in a way it is ntr cause in other routes she is your gf.
Harem obviously, different routes for certain girls too, maybe a few avoidable ntr scenes, I guess pregnancy too but we'll see. Not futa or trans that's a 100%
Actually, it is possible, but you need to repaint all the assets in the game. It is not hard but it is way too long. It's much easier to turn on the "Tint Screen" option. I'm glad you liked the story.
