AuthorThe author of Jet Set Willy wrote the game and its predecessor Manic Miner before he was 18.
MusicThe music playing in the background is If I were a Rich Man from the US Broadway musical Fiddler on the Roof, first performed in 1964.
PortsCirca 1989, Paul Taylor and Carl Whitwell worked on an Atari ST conversion of this game for Software Projects -- late enough in the title's life that the painstaking port (disassembled code read off the Spectrum's monitor and typed into the Atari's keyboard, screen data dumped as hex and dictated to a typist) was never released to the commercial market. During the same period Shahid Ahmad worked on an Amiga port that met a similar fate of obscurity.
