Historically significant for the graphics, but graphics are designed to be more than dressing: they replace text, and this was not to everybody's liking. Too many times the player does not know what an object is and what word to use, and the parser's awfulness does not help. This, plus the thin plot, the instant deaths, and the annoying forest maze, makes for low playability, but there is something in the whole concept that makes the game special. Might be the Williams' secret sauce.
