The game is below average.
The girl is disproportionate physically, and very very poorly written.
The mc, is no better.
The entire story, makes no sense at all. You want to impregnate her, because your grandma wants a grandchild, with the help of a "magical book", for... "reasons".
The entire plot, if we even dare call it that, is extremely weak.
The renders are barely average, the animations are below average.
The puzzles, are entirely unneeded, and make as much sense as the rest of the game. Every time you progress, one picture/puzzle appears in each room, for ... reasons?
The spanking minigame, is not straight forward, as is the need to "activate touch". At first, you'd think it's a magical thing, but, well, I'm not even sure, it just seems like the normal action in a couple.
This thing's not worth anyone's time.
