Blastar

Blastar was a game written by Elon Musk in 1984 (at the age of 12). The source code was published in a magazine and he received $500 for it. Ashlee Vance's Elon Musk: Tesla, SpaceX and the Quest for a Fantastic Future includes a reproduction of the page from the publication where it appeared. This version is based on that listing. Elon has since moved beyond 8-bit spaceships. "[It was] a trivial game... but better than Flappy Bird." --Elon Musk
