Playing the killer isn't as easy as you would think, you may not have the pressure of trying to survive and avoid being caught, but there's a lot of decisions to make throughout the game when you're playing. When you find a survivor you need to be quick to chase them down, survivors take 2 hits to put into downed state which then lets you carry them and throw them onto a hook, the survivors can mash the "A" and "D" buttons to make walking forward a little harder for you, but most importantly if you take too long getting them onto a hook then they will escape your shoulder, which means you need to chase them down again and hit them once again.
