Lemmings & Oh No! More Lemmings

Lemmings is a 1991 puzzle and strategy video game developed by DMA Design and published by Psygnosis for the Amiga. It was later ported to numerous other platforms. The game was programmed by Russell Kay, Mike Dailly and David Jones, and was inspired by a simple animation that Dailly created while experimenting with Deluxe Paint. The objective of the game is to guide a group of anthropomorphised lemmings through a number of obstacles to a designated exit. In any given level, the player must save a specified number or percentage of the lemmings in order to advance.
