The art student author
in question was Sandy White
, a Scottish sculptor
The game itself was actually called "3D Ant Attack", was published in 1983 by Quicksilva and was the first game to use Sandy's innovative "Softsolid" graphics engine (also used in the followup). According to a Crash magazine at the time of its release, "the animation of the figures must be the best yet seen on the Spectrum".
The game is set in the walled city of Antescher. It was one of the first (if not the first) games to allow you to chose whether to play the male or the female character. Sandy also claims that 3D Ant Attack was (and I quote) "The worlds first isometric 3D game!"
Sandy himself has made the game available for all to play at his website, http://www.sandywhite.co.uk/. He also has an image of one of the sheets of A4 paper which he used to code the game in Z80 assembley language before assembling it by hand!
As the rescued SO says in the game, "MY HERO! TAKE ME AWAY FROM ALL THIS!"
