When I choose a web font it doesn't apply this to the text for things like 'continue'. These appear just with a regular default font. Any tips on how to change this.

Try putting this in your game "start" script:

// Change the colour to orange
JS.eval ("$('#txtCommandDiv a').css('color', 'orange');")
// Change the font to Berkshire Swash
JS.eval ("$('#txtCommandDiv a').css('font-family', 'Berkshire Swash');")

For general stuff about changing the interface, look at this thread.

Thanks for that.
