Ghost Face Power......In reverse..
You know what would have been a better skill for a killer (Maybe not Ghost Face but it would fit plenty of supernatural horror icons) the exact opposite or Ghost Face's current power.
A power in which if you look at the killer they become more powerful. It would require you to divert your gaze the entire time or else face a stronger killer. Maybe have the killer have an intense terror radius in which you can tell the direction they are coming from so you can divert your eyes, but the chases would be insane when you only know the general direction of the killer but unable to see them..
Instead we have a killer like Boo from Mario. Harmless if spotted unless you decide to jump on him.
