The game isn't nearly as bad as some of the tags might indicate. Some of those tags barely have any content and pretty much all of the bad stuff is avoidable, not that there is a lot that needs avoiding. Stuff like NTR you can(and should) avoid entirely since the game offers you a major choice that puts you on a boyfriend or NTR path with a character, if you choose the former you will never see any NTR. And the necro tag is just a technicality...at one point you'll have a couple chances to have sex with a somewhat sentient zombie, you can just say no and you won't miss on any other game content or anything. Beyond some rare and weird instances the bad tags don't really have much bearing on the game. The game itself is incredibly good, you should give it a chance.
