2D Top-Down Character Movement (grid based movement, with RigidBody2D)

// This script enables simple, 2D top-down grid based character movement.
// Ensure you have added a RigidBody2D component in the Inspector and have set its Body Type to Kinematic.
// The player only moves in units of 1 on the x or y axis and is unable to move diagonally or continuously.
