Absolutely no historical accuracy.

The internet’s oldest game of tag.

THE WRONG TIMELINEFacts are optional. Jumping isn’t.

    THE ORAL HISTORY DEPARTMENT

    What did they say?

    The latest twelve lines from this run, oldest first. Times count actual play, not pauses. Kept in memory, never uploaded; a new run, timeline change, or reload clears them. Closing leaves your run paused.

    Nothing in the log. Future historical inaccuracies will appear here.

    After a run, download up to two of its last spoken lines and real ending as a three-panel comic. Generated locally, not uploaded. Long quotes may be shortened in the image.

    This replaces both timelines’ saved progress, not merges it. The page will reload and any unfinished run will end. Download your current save first if you want to keep it. Sound, chatter, graphics, and timeline settings are untouched.
