Your thoughts are interesting, perspicacious, and show just how involved you are with the story, so as a writer I couldn't be more glad. Players having a fun and deep experience is the ultimate goal here, after all.
Alba, indeed, is a good example of how much I always intend to develop characters in a story... even when said characters aren't humans, and even when the background is supposed to be that of an H-game. I must admit that I myself am incredibly fond of Alba since the very beginning, as the first Monster Girl character I ever created, and I enjoyed especially writing her events in the first two Chapters. Inspiring the sympathy of players towards Monster Girls is the first and necessary ingredient in order to explore every interaction and development that will come in the future. I'm hoping this to be an exciting, challenging and, at times, endearing experience.
Exploring the limits of humanity is clearly one of the most exciting endeavors I want to carry out in "Monster Girls: the Advent", and I'm having a great time writing about this and other themes, that will also be present in the story. True enough, if Monster Girls are in principle dangerous creatures, humans don't fall short at all, and as a big community, they can even pose a greater threat in some key departments. This idea will show itself over time, little by little... but manifestly enough.
That's correct: "And now, time to study" is my other game; in fact, I started writing it before MGTA. The setting is obviously different, but it contains quite some other interesting ideas to explore as well, in a seemingly usual school-themed visual novel.
Have a nice time playing, and I'll be here for any other comment whenever.
Cheers!
