This fairly linear game is expansive enough to make the extensive exploration rewarding while at the same time not taking itself too seriously. Nothing novel here in the way of puzzle solutions; no character or plot development to speak of, just an old-fashioned crawl through a medieval setting.
I really enjoyed drawing the map, and solving the puzzles was simple yet satisfying. The multiple endings made me groan, however, as it requires a certain action at the very beginning of the game. Let it be said that this game really has little to no replay value. (I just read the transcript to see the different ending.)
While not particularly memorable, Castle Adventure is a solid game that won't drive you crazy and is well worth a play. I think this game would be great for a beginner.
