(1) move the player unconditionally
(2) do something involve fire, or perhaps involving firing, unconditionally
(3) maybe the player waves? maybe there are waves?
(4) ???
(5) ???
(6) update the score
(7) create a new crab unconditionally
(8) storm the fortress? there is a storm?
Nothing is self-describing absent context. (I have sufficient context for "draw-score" and "spawn-crab" that I don't think they mean, say, "check scores to see if there's a draw" and "create a crab of the 'spawn' type".)
