Read full description

SPACEPLAN is an experimental piece of interaction based partly on a total misunderstanding of Stephen Hawking’s A Brief History of Time. Use manual clicks and the passage of time to create and launch potato-based devices and probes from your nondescript satellite orbiting a mysterious planet. Unlock the mysteries of the galaxy or just kill some time in what the astrophysics community is calling the ‘best narrative sci-fi clicker game of all times’. FEATURES * Fifteen starchy items to unlock, create, and blast into the vacuum of space. * Life affirming, silly story that will both captivate and help you kill time. * Reveal the secrets of five different planets across two different realities. * Banging soundtrack, as is customary in a narrative sci-fi clicker game.
