Lemmins

By Lemmins each level comprises both destructable landscape elements such as rocks, instructable sections such as steel plates, and include numerous obstacles including chasms, high walls, large drops, pools of water or lava, and traps that trigger when a lemming is close.
Each level also includes one or more entrance points and one or more exits. The goal is to guide a certain percentage of the green-hair, blue-shirted Lemmins from the entrance to the exit by clearing or creating a safe passage through the landscape for the Lemmins to use.
Unless assigned a special task, each lemmin will walk in one direction ignoring any other lemmin in its way (save for Blockers), falling off any edges and turning around if they hit an obstacle they cannot pass. They die if they fall from a great height, fall into water or lava or off the map, or get caught in a trap; they also die after being assigned the bomber skill.System requirementsOS: Win XP
