I haven't played that one.
But I did play Apple Invaders, Galaxian, Tumble Bugs, Blitzkreig, Lode Runner, gee the memories are coming back.
Almost tempted to go online (er, I am online, ok go to a certain online auction site) and see if anyone is selling an old Apple II.
But there again there are some quite good emulators around these days.
AppleWin is one that springs to mine.
And JACE.
