Jeff Minter is an English video game designer and programmer who often goes by the name Yak. He is the founder of software house Llamasoft and has created dozens of games during his career, which began in 1981 with games for the ZX80. Minter's games are shoot 'em ups which contain titular or in-game references demonstrating his fondness of ruminants. Many of his programs also feature something of a psychedelic element, as in some of the earliest "light synthesizer" programs including Trip-a-Tron.

Shoot 'em ups are a sub-genre of action games. There is no consensus as to which design elements compose a shoot 'em up; some restrict the definition to games featuring spacecraft and certain types of character movement, while others allow a broader definition including characters on foot and a variety of perspectives.
