>Break through glass with fist to unlock door.
The door doesn't have glass!
This does. But you'd better not be breaking it.
This is because the glass of your Fenestrated Plane (i.e., this window that you open sometimes), is a necessary element in your True Life's Work. Beyond its flat and doubly bisected surface lies passage to the great beyond, where there are millions upon millions of lost souls to be tracked down and saved with your recently heightened powers.
You were there at the end. So many dead souls died again, descending to the realms of double-death, which surely must be the deepest a soul can sink into a video game construct afterlife. Your life as a whimsical girl-about-town in your lovely world suits you, but deep down, you don't think you can live with yourself unless you do something for those you left behind.
So if you send one of those dainty fists glass-ward, you'll be up shit creek without a canoe.
