Mission_Impossible.pzl This level set was created by Alanfalcon@aol.com using Macintosh LodeRunner: The Legend Returns and has been checked by two people, and is possible. Barely. I can with a clear concience rate this level set at "Mind-Bendingly Difficult." The first couple are for extra lives, and are easy. In one or two of the later levels, the walking over hidden ladders trick is used.
