The name of this game, Clones 64, cannot be more accurate, since it is a clone of one of the most famous and popular games of all time: The ineffable Lemmings.
Here in Clones 64, just like the original Lemmings, you should try to prevent them from dying as many of them as possible, since they are walking non-stop from one place to another and that implies that they can fall into a multitude of dangers, therefore you objective is to put them to work trying to save as many of them as possible, whether by digging, jumping, making stairs to access another place (or to cover a danger like a hole), putting them parachutes, etc.
Therefore, apart from saving them from all the dangers they face due to their unstoppable walk, you must guide them to the exit of each level, highlighting that these Clones have a new ability that the original Lemmings did not have: they can fly.
NOTE: For the correct operation of Clones, you need to have DirectX 9.0 or higher installed beforehand.
You can free download Clones 64 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
