I’m from DOS Operating System, and from those adorable little blue and green critters who died by the thousands over many years, despite my greatest efforts—Lemmings.
Playing Lemmings in the dark at my grandparents’ house has for years been one of my very favorite memories. The goal of the game was to save a certain number of critters called “lemmings” (although they did not resemble the real-life rodents) in each level by guiding them from the entry trapdoor to the exit. Many lemmings died in my attempts to finish the game, but a few years after starting, I finally did it. I played the DOS version. The original was for the Amiga.
