"+=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.
Frustrating, but fascinating, LBM is a puzzle of a game in several ways. With a tone that swings from aggravation to black humor to horror, a genre that shifts from slice-of-life to mystery to horror, motivations that are obtuse, and metaphors that are dense, the game may be absorbing, but it may also leave a player bewildered. And, no matter how it's interpreted, the game's notion of what "learning to love yourself" means seems horrifying.
