It was a space travel game not unlike a very rudimentary (and 1-bit) version of Faster Than Light. It could be on a floppy somewhere. I still have the original 128k Mac that I built it on, but it's in storage.
Edit: Fun thing that I just remembered—the game had a picture of your space ship that showed damage to various areas during battles. The image was scanned on an ImageWriter (Thunderscan!) from a magazine photo of a Delorean, and then I used MacPaint (Fatbits!) to erase the wheels and make the undercarriage look like a space ship. Pretty awesome for those early days, if I do say so myself.
