The game is presented in a top-down perspective and is set inside a labyrinth of a complex castle. The player has been trapped inside and needs to collect three pieces of the "Golden Key of ACG" in order to escape. They can choose from three different characters; a Wizard, Knight or Serf. Each character has a different weapon to kill common enemies and access to a secret passage unique to them, meaning that navigating the castle is different for each one.
