They create safe walkways to overcome gaps. After eight bricks, you will hear three warning blips. This will give you the opportunity to reassign the Lemming to another task before it shrugs and walks off the edge of its walkway. Bashers dig horizontally, creating tunnels. Higher levels create some barriers that cannot be dug through .
Miners dig diagonally downward, again creating usable tunnels to go under obstacles.
Again, some higher-level obstacles cannot be penetrated. Level options include the ability to speed up or slow down the release of the Lemmings or increase the speed of the game. You also have an Armageddon option to self-destruct remaining Lemmings, such as blockers, that won't be moving towards the goal. The graphics are the same as the original and could have used a facelift. By today's standards, they are very plain and limited in color.
