Commentary

I'm a sucker for "construction sets" (games that come with a level editor), and a sucker for adventure games, so this would seem a natural fit. It's actually a construction set for role-playing games, though, although suited for ones containing some measure of puzzle-solving. The "language" in which the game is described is somewhat interesting; individual objects can have effects associated with them (such as summon monster, raise health, display a message, etc.,) and they can be stacked in a single square; the square can be told to trigger all the objects when the player walks over it, or bumps into it.
