I think this series is close to perfect to what you would want from rpgm porn game.
While sure amount of scenes is lacking and scenes are not rly voiced or animated, gameplay is perfect.
It is simple puzzle game but with enough difficulty to not be boring. It also has story that is not over complex to make you forget what you are playing but still has fairly nice plot.
It is also one of the few games where I have no problem with some amount of ntr and mc being "ugly bastard" (at least here he is only fat and we never even see how he actually looks). Here ntr is either with non human/monsters so you don't feel cheated, or it is actually bad end. Like this story still treats mc with respect and he still does it more then monsters.
So to individual ratings:
Gameplay 5+/5 (it is so rare for porn game to have nic gameplay that I will give it +, it is not advanced as it is still basic rpgm game but playing this game is not boring)
===
Art style 4.5/5 - yes it is rpgm game but it has nice atmosphere. And Katagari san has fairly good design.
--------
sex scenes - 3+/5 sadly it is cg style game- it has fairly lot of them if we count the cards but not card cgs have small changes only, it lacks voice acting and is not animated. + here is because they dont repeat cgs like most games that pretend to have many scenes by spamming close to exact same scenes over and over.
=======
Story 5/5 - for porn game it is perfect, who would want 10 hours story for something like this or tens of characters. here you have like 3 important characters with 3 to 6 secondary ones. Story is concise and there isn't a lot of pain in this story which is nice.
