Hehe, no... everyone knows asteroids. I've since lost the actual program in one of my frequent formats/par!@#$%^&*ion shuffles, but to go into more depth, you are a little man who walks along the bottom of the screen with a gun aimed up. When you move, your gun points sideways so you can't shoot. The balls bounce around the screen and if one lands on you, you lose a life. When you hit a ball, it breaks into two smaller balls that then bounce around as well. When you hit a really small ball, it disappears completely. I think sometimes they dropped powerups when shot, but my version didn't feature that. When all the balls have disappeared, you go to the next level, which starts off with more balls on the screen than the previous level did. Mine had really crap MS paint graphics, but the original balls were scrolling rainbow coloured, and I think the bullets may have been squiggly, duke nukem style. I only ever played it once, about 10 years ago for about 5 minutes, on a 486 at my cousin's place at someone's birthday party. Yeah good point about the passwords, didn't think of that. A profile file in %AppData%\discretion\ and ~/.discretion/ sounds like a good idea.
