Hello, the lead writer of Blood Legacy here. I have in fact played FET, and I specifically went out of my way to make this game stand out instead of retreading familiar territory. I suggested the alternate timeline angle early in the development process of this VN, since FET had already covered "What if Avatar was a dating sim?", so this needed a unique gimmick. It also allowed us to make OCs a huge focus of the game. FET is also closer to an oldschool Newgrounds porn game, while Blood Legacy is intended to be a traditional visual novel, with no gameplay outside of basic choices. Finally, chapter 3 adds some new sprites for the main girls to make the assets feel less recycled. If you have any further suggestions as to how we could make this game stand out I'd like to hear them.
