These two vintage Klonoa 2 interviews were originally featured in The Playstation and Namco Games magazines, shortly after the game's Japanese release in March 2001. Producer and director Tsuyoshi Kobayashi and art director Yoshihiko Arai discuss their approach to making a sequel, their design and development process, and new additions like the jump-assist feature and action buttons.
