Today, at 45 years old, I achieved a childhood dream by making an Atari game in assembly language: Kaverns of Kfest.
I created Kaverns of Kfest for the Apple // at KansasFest 2016, where it won the Hackfest contest. I said on the ANTIC podcast that I wanted to port it to the Atari 800, and Peter Dell harassed me to actually do it. Then he showed me how to do it. The Atari version is better than the Apple // version, of course.
