Really great write up, some comment in it why in A* we need the heuristic to be the way it is. A* is a generic algorithm but given other problem knowledge i.e.

Really great write up, some comment in it why in A* we need the heuristic to be the way it is. A* is a generic algorithm but given other problem knowledge i.e. the flat game map, an alternative algorithm selection and testing process would be a great addition. Overall great though.
