Pointer lock is now in the options, it also hides the cursor, let me know your thoughts. Fullscreen mode should be toggled with the F key, or in the menu.
On Firefox android, I don't get fullscreen after adding to home screen. Not sure the cause. Slightly better on chrome but there's still some browser UI shown. I guess it needs to be a configured as a progressive web app. That would be amazing to maximise screen real estate
