Played the unofficial translation some time ago. The writing is decent enough for the admittedly cookie cutter heroines, but it gets the job done. The scenes have a lot of variety that takes into account clothing, hairstyle, corruption level, virginity and pregnancy. The other heroines have similar variety in their scenes albeit they are a minority of the scenes.
For the negatives, the game is incredibly grind. To unlock scenes with different NPCs, you'll need to grind a lot of different stats (particularly lewdness and relationship level but other stats matter as well) with not just the MC but the party members as well. Highly recommend using Mtools and RPGM Cheat Plugin. For pregnancy while it is a mechanic with scenes and NPCs reacting to it. There could have been more depth like the MC having a monologue each night depending on corruption and number of prior births ala Violated Heroine. Also, pregnancy doesn't really impact the story unlike the previous game (see major spoiler below).
MAJOR SPOILERS
Finally the story ends with everything being a dream. Yes, the MC is trapped a nightmare scenario as part of some coming of age ritual and her friends jumped in to save her. So as expected the ending isn't satisfying as ultimately all the sex and pregnancy doesn't matter.
Overall, a 4-star game that's definitely worth your time doubly so if you have a pregnancy kink.
