I will have a look (if I can find it :). I made my own CB inspired game where you don't crush the city but carefully fire to hit targets and then a final detonator that totals the city in one nice ASCII explosion. :D
City Crusher, original game, 1983 Your Computer magazine.
City Crusher Arcade for VIC20 + 3K
I'll try soon your game. I like very much blitz style games.
Added a link to your game in my City Crusher Arcade page. :)
