It's actually fine? for me at least, and I guess the reason of that is beacause most of us take it as a porn for wanking like some other fnvs( especially those from Japan), which are easy to read and their plot are simple, so it comes to natural people lose patience among the 'obscure' texts and terms.
However, I think the delicacy and stunning artistry you build for the game is the thing that makes it diffrent from ALL other similiar ones, plus the plot is so well excecuted and arranged, these all make me kinda feel the sexual contents are just the flower on the cake but not the cake itself, I' ll be very superised if you tell me they are all finished by your own.
