Dive to the Heart
Dive to the heart is the first place you visit in Kingdom Hearts I. Here you learn how to play as Sora as well as chose your starting stats. The world is basically huge platforms that have pictures of the seven princesses of heart for Sora. For Roxas the platforms have pictures of Sora, Riku, Kairi, Goofy, and Donald. You travel throughout the world fighting either shadows as Sora or dusks as Roxas. At the end Sora fights Darkside and Roxas fights Twilight Thorn.
