I'm really loving this game so far (up to chapter 2).
The main (and so far only) love interest model is unique and facially realistic, not just some forgettable off-the-shelf perfect 10 you've seen in a thousand other games before.
The main fetish is obvious from the beginning. Anal. A lot of the dialogue focuses on that, even if there is no actual penetrative content with the main female character so far. The dialogue and renders are very hot if you enjoy this tag.
The dialogue is as others have said obviously not the work of a native English speaker, but that works in the context of the story when both the characters are recent immigrants from wherever the dev is from to wherever he imagines they live now. They're speaking a second language, so it works and adds to the realism and eroticism.
The only thing that I worry about is that you get to say what the relationship is between the MC and the LI is at the start, and I think the dev obviously wants you to say it's a mom-son relationship. I don't want any of that in the games I play, so I'm hoping he doesn't fuck up the English in future releases so the woman says things like "Yes, suck my tits like when you were a baby and I was your teacher" like he did in his last game.
Also, this game desperately needs urination content. Missed opportunity so far. Get these characters peeing in front of each other, please. It would totally work in this story.
