Jack Nano & Daisy Worlds

Jack Nano and Daisy Worlds is an advergame developed for C. & J. Clark to tie in with the company's line of school shoes for children, whose main selling point is a miniature toy hidden in a compartment under the shoes' insoles. The app comprises a series of mini-games centered around the eponymous Jack Nano and Daisy characters.

Jack's story is set in a futuristic, science-fiction world ruled by a tyrannical horde of "nanohunters", while Daisy is a stereotypically girly would-be fashion designer.

Further tying in with the brand are codes included in specially packaged Jack Nano and Daisy shoes, allowing players to unlock bonus content and power-ups to be used in-game.
