You could make endless directions. The animal class in the Little Crab game from the book has a "move" method with makes the actor move in the direction which it faces right now.
I have a little suggestion: It will be good if the lobster would go in the direction you turned. In your game are only 8 directions possible which makes it hard to play.
In the counter, I changed the the top from private to
public static int value = 0;
public static int target = 0;
Then i made all the animals that are relevant to the counter as subclasses of the counter. I just need to use add(x) to add x to the counter. I did not understand how to do it without using subclasses.
