Use the arrow keys to move Barney to the left and right. Try to catch the bones! Expand the game by: 1) changing the variables on when the bone appears and how fast it falls; 2) Barney is a fussy Westie so take away the score when the bone hits the grass; 3) Add other objects/sprites to the game, e.g. a special bone that appears randomly and is worth double-points.
