Last Christmas

Publisher's blurb: You're a time-travelling ghost, you killed Ebenezer Scrooge by mistake, and now the apocalypse is knocking at your door. Will this be the LAST CHRISTMAS? Take control of the three ghosts of Christmas (Past, Present, Yet To Come) and the phantom Jacob Marley as you skip back and forth through the timelines to fix your mistake. After accidentally giving Scrooge a fatal heart attack, you awake to find that the world has ended. Can you visit Christmas Past and undo whatever it was you did, or will this be the LAST CHRISTMAS? A one-page RPG with incomplete rules for time-travel.
