Becasuse playing better will make incorrect and inaccurate visual indicators suddenly become correct clearly....

Well, that statement isn't entirely wrong. I'm sure there are people who could beat say Demon Wall with their monitor turned off. That doesn't mean showing you a blank screen is a good way to represent the world. You shouldn't have to play better to overcome the game's deficiencies.
