Played this immediately after the "Deep Sleep Trilogy" and was slightly less enamoured with the premise. Decent enough puzzles but the ability to do something wrong without knowing you'd made a mistake until the end of the game leaves a somewhat bitter taste. The first game of the trilogy is short enough that having to replay it is no big deal but later entries have plenty of useless items/tasks that mainly serve to confuse the player or cause a "Bad Ending" state.
