I have seen some games that after undo say: Undoing taking the idol or Undoing going north instead of the generic “Previous turn undone” I have looked at some undo control extensions, but some wouldn’t run, others still couldn’t actually tell me what action had been undone. It this at all possible in inform 7?
What you’d probably want to do is record the “current action” in a global variable each turn, then use one of those extensions to make a “before undoing an action” rule that prints that stored action. You’re using 6L38?
