Improve headings, add rules (HTML) and refine aesthetics (CSS)


You could also improve / modify game mechanics (JS), such as:
  1. play test, and better balance the game mechanics by adjusting the random max and min values
  2. add other abilities (e.g. magic)
  3. allow pickups or items than can be used as one offs to assist
  4. locations / bosses?
  5. story?
  6. store where i can trade items? etc.
