Game is pretty direct and doesn't lose time to start pouding the main character. Pretty good porn fapping material but if you're looking for something more complex then it is not for you.
Is it good porn, though?
If you're looking for a good fap then it is marvelous, just what you're in need of. The main character is pretty hot and all the h-scenes are good, some are great. The lewdness level is a pretty strong feature as well, since as you character gets more and more harassed she tends to dialogue more in favour of being fucked and some of her dialogue is pretty hot.
Is it a good game?
Gameplay wise is almost like a porn version of Ao Oni (remember this one?). When the character hits you, the scene starts and you gain some lewdness, if you get to your limit Ruruka goes back to the village. No pointless boring dialogue (which is pretty common in porn RPGM), no combat at all, just you running from (or blatantly touching them) the enemies as you try to progress further into the dangeon.
Overal it is a pretty good game, with great images and good porn. I see myself going back to it but it is not for you if you're looking for something more complex and with a lot of systems.
Obs: the game says that if you collect all the scenes it gives you a tiny extra. It is really really tiny and for me it is not worth going after it.
8/10
