VERY EARLY ACCESS

EST. A REALLY, REALLY LONG TIME AGO

RUN FOR
YOUR PAST.

A PRE-HISTORY ORIGINAL

One dinosaur. One determined caveman.
Absolutely no historical accuracy.

The internet’s oldest game of tag.

THE WRONG TIMELINEFacts are optional. Jumping isn’t.

Removes humans, mammoths, and inventions. Switching timelines resets the run. Each mode has its own personal best.

THE LOCAL MUSEUM OF QUESTIONABLE DECISIONS

Make a mistake. Become art.

Your last six failed runs become paintings on passing rocks. Save a postcard to take one with you. Generated on your device, never uploaded. No historians were consulted.

A pristine cave. An unblemished record. Give it a minute.

A FIELD GUIDE TO CHRONOLOGICAL CRIMES

Been there. Barely survived.

Survive seven different Chaos encounters to complete your journal. All three evolution forms count separately. Saved only in this browser, independently of your scores and cave paintings.

    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 only; a new run, timeline change, or reload clears them. Closing leaves your run paused.

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

    A QUICK FIELD GUIDE

    Stay one step
    ahead of history.

    You’re the dinosaur. The caveman behind you has a club and absolutely no chill. Jump over the cacti and rocks to keep the chase going.

    The longer you run, the stranger things get. Evolution rounds bring real obstacles after a short briefing. Other encounters give you a breather. Historian mode removes humans and other chronological crimes. Your records and cave paintings stay in this browser.

    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.
