I like how some games that employ cheap tricks, its ok, than when others do it, it's wrong. For instance in demon souls when an enemy is pretty well hidden and pops out and kills you or throws something at you and kills you from a distance. and you never even saw him. This is your fault and therefore its a hard game, when it's really got nothing to do with difficulty at all or skill of player. It's just an unforeseen thing..Yet this game does something thats very traditional in 2d platformers and its a cheap 2d platformer trick.... Nothing to do with making the game harder.
