You could set the"fullscreen in browser" option in the project properties to off, that way the game will be played within it's original frame on desktop..
on any touch - is on mobile - browser request fullscreen..
That way fullscreen can only be achieved on mobile..
Ah yes, that is what I was trying.
But full screen on mobile (via the browser object - I have tested all stretch scale options) is zoomed in or something. The game is unplayable - you can not see anything.
Edit: I just found this:
in your HTML code, add the following meta in the <head> of your page:
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />[/code:sn6a8qyv]
