Basically a bunch of logical puzzles (where "logical" means "related to formal logic") held together by a (hair-thin) plot thread. The problems one has to solve vary in difficulty from "tough" to "Aw! Impossible!", and
made personally me think the enclosed walkthrough was a blessing. Can only be recommended to real fans of that kind of puzzle.
