You Are Amazing! I saw your talk at Toronto Commodore Users Group, and I am complete impressed by you're skill. I started with Apple II at home and Pets at school, and knowing those platforms, and what I have learned from 45 years of programming, my hat is off to you sir, for making games like all of these on the Pet (and C64) patform.
One semi related question: when I was playing/programming on the Pet, there was an adventure game that had battle animations, like spiders moving back and forth in petsci graphics. Do you remember what it was called? I spent a semester obsessed with it, and I would love to find a copy to play with.
Cheers, James
