# ║ Instructions:                                                      ║
# ║   Using code from Syvkal's Ring Menu                               ║
# ║   I created the title screen menu                                  ║
# ║                                                                    ║
# ║   If other options are added, it will require changes.             ║
# ║   Icons must be in the format of ''choice' + space + icon'         ║
# ║   example                                                          ║
# ║   'yes icon'.png or 'no icon'.png  - without quotes                ║
