Theres a reason why its called porn games. What the dev did here however was not really a game.
The dev itself is actually a manga drawer and not someone who makes games, so its understandable that the game is therefore shit.
The Art and concepts were all reasonable hot, which is why I'll give it an extra starand and the fact that the heroine gets new weaknesses based on her experiences is very arousing for me, especially, because she is a nun.
The game part however was just done so horribly, there really is so much to say, thats at the same time I have no idea what to adress really.
I'd say that the story writing is good for a short 20 page hentai doujin, but in terms of an actual story which is supposed to be good: 0 points, I'd even give negative ones. Extremely shallow, complete nonsense and boring
the game play wasn't any better, but at least it wasn't very annoying. It was simply boring, walking 5 minutes till your goal and there we go, next stage.
The only "challenge" here was to "avoid" the enemies on the way to your goal, which didn't even engage in battle, they just straight up started molesting you and you get to choose if you wanted to get molested or not.
Still, personally I like this game, as it is very in my fetish range, the art is a bit offsetting as I don't like it that much, but Anime Nuns with monsters and shit you know.
I would after all that still recommend to try playing it if its in your fetish range, since "gameplay" wasn't that important for me anyway. I just wanna fap and go on. This game was pretty good for that.
Noting interesting in this game, just pretty hot (for the right people)
