The Lemmings game for NES is a logic arcade game originally developed for the home PC, and later re-released on various platforms, including the NES.
Lemmings gameplay is pretty non-standard on NES because it was originally designed with PC mouse control. The NES and other consoles use a joystick crossbar to control the cursor, which is more difficult to control than a PC mouse.
The Lemmings' group usually consists of 10 or more characters who move in a free path to any available locations on the level. The player must choose a command depending on the situation and give it to each Lemming individually. For example, when jumping down from a high platform, it is necessary to give each Lemming a soft fall command, otherwise he will crash. In this way you must guide the Lemmings through all levels with the least amount of damage.
