Using Unity, implement a two-level finger-four formation with four characters (shown below).

When the user right-clicks on the plane, it should create a player-sized obstacle that characters cannot path through. When the user left-clicks on the plane, the formation should use a modified kinematic arrive method to move to the spot of the click. Characters should avoid the obstacles (without using pathfinding) while maintaining their position in the formation (see two-level formations).
