I'm few days behind, but today (10th day) I solved 8th day puzzles. I also went to see on which step each "??A path" reach ??Z node. Thankfully each of them reach only one ??Z node on N step, and then after another N steps reach same ??Z node. I think that if first N was different from second N or if each "??A path" after reaching first ??Z node reached different ??Z nodes, it would be terribly difficult.
