This Infocom game is directed towards younger players but is appropriate for adults; in fact, the game is still very challenging. The fantasy elements are charming and fun (and sometimes pretty creepy): an army of boots, a witch who steals cats, ghosts who murder you...
All the puzzles can be solved with sufficient exploration and minor logic; I missed a few areas and items in my exploring, though, because the world is rich and beautiful.
As far as I can tell, the game is for beginners because there are only the n,e,s,w directions (no ne, se, nw, or sw); most puzzles have multiple solutions; most items are easily visible (except for the most important one); and death won't come unless you have been repeatedly warned.
The game is split into two sections; one where the player explores a quaint village with minor annoyances (such as locked gates and a poodle); and a second section where the village has turned dark and evil (with murderous ghosts and a hellhound).
As many have stated, this is a memorable game, more so than most of the Infocom games I have played, or interactive fiction in general. As usual, I played this game on the Lost Treasures of Infocom app on the iPad.
