Much better than would be expected, considering that this game was designed by committee. On the one hand, it contains a few genuinely creepy moments, some clever puzzles and bits of evocative writing. On the other hand, it contains way too many disparate settings and the quality of the design, writing and implementation varies widely between the different story segments.
"+=3's" thesis is that a puzzle's difficulty is not directly related to how logical the solution to the puzzle is, but rather by the context that the puzzle appears in. Most seasoned IF players will find this game's one puzzle infuriating because it cleverly defies IF's conventions, yet the puzzle's solution is not only logical, but, literally, a cliche.
