Spooky (spoopy) themes are always tough, and Dolls... yeah. First thing I did was hit ye olde google and look for synonyms. Several tickled but didn't quite work. Then I hit effigy.  A sculpture or model of a person. Or more specifically, something made to be destroyed in representation of someone.

How horrific is that?

And in general, what is a doll? Something we pour a bit of ourselves into. Wish fulfillment. Escape. A chance to be different. Perhaps even to transgress without angering the world around. Or, perhaps, to pour your imagination into someone else. See through another set of eyes, represented by the doll. Maybe even used as an effigy as you put it through trials. Dorian Grey with less paint and more mass.

So is this game something about building an effigy, or being one? That I need to explore, and find out. We'll see how it goes.
