What is Lemmings?
Originally developed for the Commodore Amiga, Lemmings is a puzzle game in which the goal is to guide a certain number of Lemmings to the exit on each level. The Lemmings enter the level through one or more hatches somewhere on the level. They can be assigned skill that are used to help them get to the exit. The levels get progressively harder, with some of the last levels being VERY difficult.
