We consider graph searching games on directed graphs and corresponding digraph decompositions. In particular we show that two important variants of these games --- underlying DAG- and Kelly-decompositions --- are non-monotone. Furthermore, we explore the limits of algorithmic applicability of digraph decompositions and show that various natural candidates for problems, which potentially could benefit from digraphs having small "directed width", remain NP-complete even on almost acyclic graphs.
