The popularity of the game on the Amiga (initially released) led to its rapid porting to many other platforms: Panasonic 3DO, Acorn Archimedes, Amstrad CPC, Apple IIGS, Macintosh, Atari Lynx, ST, Commodore 64, Amiga CD32 Amiga CDTV, MS-DOS, Nintendo's NES, SNES, Game Boy, Game Boy Color, SAM Coupe, Sega Game Gear, Sega Master System, Sega Megadrive (Genesis), Sinclair ZX Spectrum! and it is considered to be one of the most widely-ported video games of all time. The game is divided into a number of levels. Each level comprises both destructible landscape elements such as rocks, indestructible sections such as steel plates, and numerous obstacles including chasms, high walls, large drops, pools of water or lava, and booby traps. 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-haired, blue-shirted lemmings from the entrance to the exit by clearing or creating a safe passage through the landscape for the lemmings to use. Unless assigned a special task, each lemming will walk in one direction ignoring any other lemming in its way, 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.
I would expect better results on graphics for the ZX Spectrum version. Each level, although it uses some of the original (Amiga) details, colors are very limited here (each stage uses one or two colors max!). But still, it features great animation of the tiny lemmings! Graphically the best 8bit version was by far on the Sam Coupe due to its advanced hardware (well a CPC+ version was missing!).
The sound is offering a nice intro tune, whilst there is no in-game sound at all! The game was probably written to run on 48k version, ignoring the existence of the 28k machines (which could easily use, at least, more sound data). Eitherway the game is very playable and offers great fun when running on a ZX Spectrum!
