                # x co-ordinate, y co-ordinate, and color of the pixel

        for px_info in info:
            self.fill_rect(size*px_info[0] - (size-1)*x , size*px_info[1] - (size-1)*y, size, size, px_info[2])

You can add this code to increase the font size, but this is the default pixel font and there is no other style.

Thanks so much for your help!
