This HTML5 game/greeting card is designed to celebrate Mid-Autumn Festival, a Chinese traditional festival. Among all the legends associated with the festival, Goddess Chang’e Flying to the Moon is the most wide-spread one. The reason we choose long goose as the main character is that Long Goose shares the same Chinese pronunciation with Chang’e. While Chang’e flies to the moon, long goose explores the universe. Enjoy the game, and, BTW, don’t miss the credit cookie!
