In which direction did you think you will take that adventure with your little girl, before you started ?
I mean the tone of the whole thing and the goal for your little protagonist. I cant imagine playing with a kid anything that involves heartbreaking losses (dead neighbours, lying on their frontlawn and horrible stuff like that), severe injuries, etc.
In a fantasy-game, things could be more "nice" to get around the treatment of injuries ("Its magic!") f.e.
The only approach i could come up with, would be like a humorous One-shot in the tradition of the "Simpsons Halloween Specials" ("BARTOCALYPSE NOW")
So i am interested to know how you go about these things.
PS: Hope your tooth will get well soon & have fun with your daughter playing
