Found these the other day. They are free games - an affectionate look at Adventure Games. Obviously, I thought of Alrik immediately, but I figure others may like them, too:

Adventure: The Inside Job

Adventure: All In The Game

Obviously, me being me, I played them in the wrong order, so I can definitely confirm that they are totally standalone. But I put them here in the RIGHT order, as they may well be more enjoyable played that way! \:D
