Deflex

Deflex, also known as Super Deflex, Deflex V, and Made In France, is an arcade puzzle game developed by Jeff Minter. (Not to be confused with the drum & bass producer 'Deflex' formerly known as 'The Darkest Fellow'.) The first version, developed in 1981 for the VIC-20 and Commodore PET, is generally considered the first Llamasoft game ever produced (although Jeff Minter did develop some incomplete early titles under the name JCM Software, but these were never released).
