Sorry for the delay... There is no email advising me of new posts so I just see the messages when I come around. The fonts used in the theme are not taken directly from google fonts, instead, I download the .ttf file and create the .woff and other formats manually. This way there is no Google dependancy and the site loads much faster. If you want to change the fonts you have to do it manually, first, including the necessary files in the /assets/fonts directory, the same way I did with the ones included, and then, writting the necessary markup in the CSS. I know it is a bit tedious, but I wanted a non-dependant theme. If you have further questions I'll be glad to help.
