I've done one playthrough of the game so far. One playthrough will last like 20 minutes.
-The writing is quite good. The ruthlessness is well conveyed. The scenes could be a bit longer but I will expand on that in a bit.
-Picture selection is good. Nice looking girls and gifs.
-The overall plot, theme, and kinks are as you see in the tags. You will enjoy it if you are male dom rapey stuff.
-The game is simple to play. You impregnate girls for 7 nights and get one of 20+ endings.
-As far as the ending, at least the one I got consist of one page with a picture and a couple paragraphs of text. Not too satisfying.
-As for fappability, I personally couldn't even though these tags are my favorite. The scenes and writing are good, but its too short and there is very little build up. You meet someone you seduce/rape them 3 pages later.
I found the game pretty good and will play a few more runs of it, but I'd imagine that it will get boring after 3-4 runs. There is a limited number of girls you can chase, and after you've seen it all over several runs, the only thing left to do is look at the guide and meet the condition for one of the endings and just keep sleeping (I think). It looks like there is some NG+ bonuses that could alter the course of the run in a significant way, but the fact remains that you probably would have seen all the scenes with the girls and would skip most of it after a while.
The flaw I see is that the main gameplay portion is too short and limited to match the multitudes of endings and playthroughs the game requires. Take this review with a grain of salt though, because I only played one run so far and the conclusions I made was from that and looking at the guide.
