Story story = parser.getStory();

IGame game = new ConsoleGame(story);
game.play();

Implement the IGame inteface to create your own GameLogic

public class SimpleGameSkeleton implements IGame {
    private Story story;
    private HashMap<String, String> variables;

    public ConsoleGame(Story story){
        this.story = story;
        this.variables = new HashMap<>();
    }

    public Story getStory(){
        return story;
    }

    @Override
    public void setVariable(String variable, String val) {
        this.variables.put(variable, val);
    }

    @Override
    public String getVariable(String variable) {
        return this.variables.get(variable);
    }

    @Override
    public void outputNormal(String text) {
        //TODO
    }

    @Override
    public void outputSpecial(String text) {
        //TODO
    }

    @Override
    public void delay(long delay) {
        //TODO
    }

    @Override
    public String outputChoice(Choice choice) {
        //TODO
    }

    @Override
    public void play() {
        IStory obj = story;
        while(obj != null){
            obj = obj.execute(this);
        }
    }
}
