The whole thing with Eliza being a vampire seems really unnecessary. Something better would have been to use her as someone who helps the MC not succumb to the darkness, and if you wanted to make her strong, you could have her learn magic or something like that.
Although, considering that choices matter little and it seems more like a kinetic novel, I don't know how the developer would handle it.
