I have marked my HTML game to Start full screen. How do I programatically exit the game with javascript from within my HTML game? I want the user taken back to my game's page that they see before clicking Start Game.

I am not sure but is there any difference of fullscreen itch than any other page? 

Tried "document.exitFullscreen();" ?

The start fullscreen isn't actually that kind of full screen. It just tells itch to give the whole browser window to my game.
