Williams' success with APX led him to create several games for Synapse Software, including the beloved Alley Cat and the incomprehensible fantasy masterpiece Necromancer, before moving to the Amiga, where he created the experimental Mind Walker and his ambitious "cultural simulation" Knights of the Crystallion.
Necromancer, Williams' later creation for the Atari 800, plays like a fever dream—you control a druid fighting off spiders while growing magic trees and battling an undead wizard. It makes absolutely no sense by conventional standards, but it's brilliant in its otherworldliness.
"The first games that I did were very hard to explain to people and they just kind of bought it on faith," Williams said in a 1989 interview with YAAM (Yet Another Amiga Magazine), suggesting this unconventional approach started early. That willingness to create deeply personal, almost surreal experiences defined Williams' work throughout his career.
