Mouse movements, testing

Following the user-testing, I changed the movement controls from WASD to mouse. the user points with the mouse and right clicks to set a destination. Once clicked, the avatar progress to the destination without stopping. This was not my initial intention, but a result of some logic from the WASD code. By I decided to keep is as it manifests the roguelike nature that once the player makes a decision they cannot change their mind and needs to face the consequences.
