Clones 64 is a clone of one of the most famous games of all time: Lemmings.
Here in Clones 64, the same as in the original Lemmings, you have to try and avoid as many of them as possible from dying. They go past you on all sides, and you have to be careful or they´ll all be in a variety of dangers. Thus your objective is to make as many work as possible to save their lives, whether excavating, jumping, making stairs to access other places, blocking a dangerous place like a well, wearing parachutes, etc.
Not only do you have to guide them all away from danger, but you must also guide them, at the same time, to the end of the level. Clones 64 has an ability that the original Lemmings didn´t have: they can fly.
In order to work correctly, the program needs you to previously install DirectX 9.0 or later. If you don´t have it you can get it here:
