As for "NTR"; Everyone appears to have different view of what is NTR,
Sure, but I do believe what I said is agreeable to pretty much everyone. I mean, if MC has (literally) no love/sexual interest in his mom, how does that count as NTR? Even if it changes later, which I don't think will happen since we are already on ep 5 and even the side stories feel the same, the beginning of every game is important.
I don't think playing the NTR route is worth it since it seems to lock you out of content/interactions with the mother in order to give you scenes that are just the mother "prostituting" herself and have no NTR feeling.
Another thing I didn't like was the alpha points locking you out of further interactions. In the last scene with Sarah, you could have had more fun with her (maybe first sex scene) if you had it or had to stop if you didn't, which kind of sucks since the game barely has any content. Also, in the NTR route you are locked out of gaining any alpha points.
That's my point of view after playing the entire game till now. I still believe the dev has barely any understanding of NTR but still decided to make it to attract more people, and the alpha points thing ''apparently'' forces you to play it's route or replay the entire game to be able to see, like, half of the game scenes that you're missing out, which kind of sucks. NTR route experience was very poor, I hope it gets better, but I don't think I'll have interest in playing any further updates.
