Make the back button restore the story and keep dice results

A rewind button that only moves the text back leaves points and flags from the undone choice behind, and one that also replays dice lets the player reroll until it works. Here is how to rewind honestly, with a limited history and fixed outcomes.

Why this works

Going back is only trustworthy if it returns the whole world, so each step keeps a real copy of the position and everything that was counted. Dice are the exception: if they changed, going back would become a way to shop for a better outcome.

When not to use it

Wrong when the story is about irreversible choices, such as a permadeath game or a narrative whose weight comes from not being able to undo. Leave out the back button, or limit it to the dialogue just read.
