My review:
Honestly, most "last man on earth" scenarios are silly and simple. It would not likely be a sexual smorgasbord for a surviving male from an advanced civilization...a single sperm sample can impregnate lots of women and there is ample supply. A man's likely fate would be sequestration and daily milkings.
That being said, this guy sure isn't getting any action. The Daughters of Evolution are ripped off from "Y the Last Man" but they could happen irl. But this guy gets no love from anyone else, except his dau...uh...his chil...uh...his bitch. She's his bitch, he's her boo. Well, and one other woman after you do her enough favors. I could see this developing into a "Superpowered" style grind. Not good.
Meh. The interface isn't very good and the lack of rollback in case you missed a pose is unfortunate. This point and click, drag and drop stuff was new in the 80s. This could be done better and more smoothly.
Working through all these so=called "episodes" to unlock kisses and boob flashes is lame. The lackluster story is not good enough to skimp on sex options. I expect better from games in 2019.
Edit: Forgot to add that the sexual content includes the stupid, overused, stupid, tired, stupid, rapey "sleep sex" that we see in every retarded incest clone. Bonus, it is mandatory to progress the lame ass "story." So you get to be a total fucking creep as well.
