We think we have covered a lot. We said we had the full level, but it is not quite true. We still have two dilemmas ahead: starting and finishing the game. Take a moment to see how the beginning of the game is to be created.
We have assumed that the player will begin to go forward, but we have also said it was important to cover all possibilities. What if the player decides to go back just to start? We will also cover that possibility. Are you one of those players who prefer to explore the environment before they start playing the game? Ahem! No comments about it except that we have a problem now—not you, dear reader, but the potential options. We should cover any possible way out. We must force the whale to go forward, and it should have no other choice but to go in a particular direction.
