I'm so happy you made another game! It's practically perfect, I love it already. I did notice some bugs though like the locket is always in the nightstand even when you already took it or that when in the scene where you can pick your prosthetic color it seems to only acknowledge the right leg even when you have both prosthetic legs. And when it talks about the ballet shoes it only talks about the left one.
I mean you don't have to stick to undertale if you don't want to but maybe Fresh Sans would be cool to add, like you just encounter him ? I dunno. Maybe also horrortale. I think what also might be cool is like a side(?) mystery, you might already have that planned I have no idea but still. Though it might not work with what kind of story you are going for if you it's like just romance or fluff or something.
