Do you have a computer with a drive for 5 1/4-inch floppy disks? The game came in that format and had copy protection that wouldn't allow it to be run from anything but the primary floppy drive.
Actually, using my work's Apple IIe, we were able to copy Disk 2 onto a blank floppy and run that one in a second drive, so you didn't need to keep swapping disks. Really sped up the game! But yes, Disk 1 was deliberately copy-protected.
Text-only games would probably seem very tedious today.
