I wouldn't say the story is light, I mean the visual representation is pretty fuckin scary lol. Anyone who's played video games with hive mind flesh walls and fuckin' face hugger-esk monsters, usually never ends well. Also doesn't help there was part in the game where you Yuri yourself in some freaky dream sequence. Kinda reminds me of Body Harvest for the n64.
Graphics are important to an H game, but ultimately such things are subjective. Can't really tell a person to like something, or 'teach' it outside of just having them consume and garner wisdom over time to have change happen. Gameplay is something you have to enjoy from a gamer's perspective, and that's also something of subjective preference. At least, for H games all that's important is that the gameplay and the H content go hand and hand together, which in this H game it does so rather well now.
As a side note, I hope there's variants of the creatures she gives birth to. Probably a lotta work so maybe keep it to unique enemies? It would be nice to see all the same.
