The conflict is that in the real world, people have momentum. They take a bit of time to change their velocities. In video games, we are accustomed to sprites that can instantly change velocity and sometimes go from motionless to moving significant distances in a single frame. The publisher wanted both simultaneously. They wanted the human player character to instantly change direction in response to controls. But, they also wanted the character to move like a semi-realistic human who has momentum and takes a while to change directions instead of like a sprite that instantly changes direction. :/
