Not going to lie the reveal for the Frankenstein killing the little brother feels off. When we first saw him speak (which was a big "oh shoot" moment), he sounded mature. As he continues to speak and he reveals he strangled Will, it doesn't sound like him. Make sure you keep his tone consistent!
I didn't read the book so you can correct me on this. If we're not playing as Frankenstein, why do we play as someone who has the last name?
I feel like the choices were good but maybe you should consider going more into the creation process of Frankenstein. Yes, we worked with the foot and the fun is making im come to life but what about the building process. How did we get the heart, and, the brain, and the eyes?
