Hmmm... even though I'll be out of town the majority of this challenge, I'm already getting some interesting ideas with this one.
Mostly just the idea of a big, Bronze nanny that has to take care of a boy (and vice versa), sort of a Ico-type relationship, but instead of a defenseless girl and a young boy... an indestructible girl and a young boy

. The statue has a look of pleasant wisdom about her.
We'll see where it leads, but so far I am liking the idea of it being a more puzzle-oriented game. The Nanny can obviously walk through hazardous materials, take damage, lift heavy objects, etc... hmm.
I'll tinker with the idea, but no promises. Like I said, I'll be out of town for the holidays for most of this challenge. Good luck to all the entries, however.
