It would be nice to see a continuation of that game, a little more elaborate, with the protagonist learning to use other vampire powers, how to compel and turn the girls into vampires. I believe that in a more "realistic" situation, Marianne would eventually abandon the MC, for not being transformed into a vampire, in a scenario of vampire stories, the ideal to transform while the character is still young, between 21 and 28 years old, so as not to grow old and keep looking good.
