The first enemies you fight are these demon girls who will try to force you to impregnate them. If you do, they evolve into a more powerful enemy with new abilities that I will not spoil. Very cool!
This game is not good at all from a BF perspective. if you're going into that game for BF you're wasting your time. It's incredibly lackluster.
With that said people seemed to like the game in general, so you may still find it appealing in other ways.
