Californium is an exploration game co-developed by Darjeeling and Nova Productions, and released in February 2016 for Microsoft Windows and OS X. Californium was developed as a tribute to science-fiction author Philip K. Dick on the 30th anniversary of his death. The player controls Elvin Green, a struggling writer dealing with family matters, as he discovers the means to manipulate reality, and explores several surreal landscapes. (wikipedia.org)
