Yeah, I thought of this approach, but it smells funny to me. It doesn't seem much different from putting the game in a modal sheet, which also strikes me as wrong.
But maybe that's the right thing to do.

This can be quite a nice way to show you are no longer just 'navigating' but you are now in a different state of 'playing'. Since it's your own button you can get the action message from it, pause the game, pop up your 'do you want to quit?' sheet and do the necessary.

When just navigating, the left button is Back and the right button is Edit, when you hit Edit, the left button becomes Cancel and the right button Done. As well as showing what mode you're in and being clear about it, it prevents you going back until you actually get out of edit mode.
