Sorry, probably not? I would have had to design the game from the ground up to support that. But initially the idea for the game was to have very tough choices, and if you can always roll back – no choice actually matters.
So it wasn’t a feature I was planning for. Right now it wouldn’t hurt too much, but the game fundamentally doesn’t support that right now.
But I’ll look into it and see what it would require to get working. It might require rewriting the whole core of the system, in which case it definitely will not be implemented.
