Webfonts not working

Hi

I've been trying to get custom webfonts into my game for ages, but to no avail.

All the fonts show up as the webfonts when I run it but if I try to upload the game to google drive and play it from there, the fonts are set to the default Arial.

Here's a screenshot of setting the webfont: puu.sh/6QxLo.png

What am I doing wrong? Or is it just bugging out?

thanks!
