As you navigate through various captured levels of Sanrio Town, you'll battle against the block troops and their minions. You can also team up with a computer-controlled partner, such as My Melody, Purrin, or Monkichi, each with their own special attack or ability to aid Hi Kitty.
As you progress through the game, you can unlock bonus content, including movie clips and music from the game. Additionally, you'll be able to unlock character bios on various characters in the Hello Kitty Universe, as well as new outfits for Hi Kitty to wear and new weapons for her to use.
