User Summary Puzzles created by Zachtronics Industries have created a sub-genre of puzzle games all their own fondly called Zach-likes. In Prime Mover, a Zach-like, you have an open-ended puzzle environment to complete science inspired circuit puzzles using a variety of techniques including nesting circuits inside other circuit parts. It is all pulled together by a loose story. Difficulty starts out easy and ramps up quickly as more and more concepts are added to the puzzles.
