Ladybug Pathfinder comes from Yutaka Onizuka. It's a topology puzzle app game where the object is to place the Ladybug on any node and then trace a path that covers every  line once.
  We've seen dozens of these types of puzzles. However, this is the first one that has a 3D perspective.  Also, the graphics are simply terrific. There are 110 puzzle and I've done 32 of them. I have to stop because these are too easy. Nevertheless, the visuals are, again, wonderful.
