Lemmings is a puzzle game developed by DMA Design (now Rockstar North) and published by Psygnosis in 1991, originally for the Commodore Amiga.
The popularity of the game on the Amiga led to its rapid porting to many other platforms, and is considered to be one of the most widely-ported video games of all time. [Info taken from wikipedia]

It seems that they had planned on using a trackball and buttons to control it, though my friend optiK and I have been discussing that it seems to be based more off the genesis build than anything. Still, it feels somewhat incomplete…
