Master (o) Piece productions here. This is a level map for the popular computer game, Lemmings, turned TI by Matthew Roberts.

This level pack is possible to complete, but will make you think. Fake exit doors, blocked digging paths, etc. exist to confuse you, and you will have to try many times to complete 
this pack as you have to complete each level with the bare minimum lemmings, and you have to make each lemming out of 20 survive and by the end of this pack, you will have only 14 lemmings left.
This is a challenge that is suitable for long time players or beginners (but not for people that have an IQ of a dead moth) Happy playing!
