Where to go from here

The framework is designed for you to have fun while continuing to learn Java and gain experience programming. Here are a few suggestions for adding to this little tutorial game.

• Add some more rooms to the maze. It is a maze after all, and should probably be a more complicated.
• Add a healing fountain that will restore the player's health when visited one time only.
• Add some gold to the maze that the player can pick up. This will also require that the Player has a gold counter and some accessors.
• Add a merchant who sells a sword to give the player an "edge" (har har) when fighting the goblin.
• Make the goblin tougher to fight, which might require you to also implement some of the above suggestions.

Add some pizazz to your screens

While console games cannot compete visually with modern video game graphics, a little color and sound go a long way. The ConsoleColors helper class has some ANSI codes that will add color to the text on your screen. And adding sound to Java programs these days is easy.

Replace the code in your WelcomeScreen with the below code. Note that several of these methods have more than 20 lines of code each and are in need of some serious refactoring/cleaning.

WelcomeScreen.java

package docrob.cag.mygame.screens;

import docrob.cag.framework.screens.Screen;
import docrob.cag.framework.screens.ScreenManager;
import docrob.cag.framework.state.Game;
import docrob.cag.framework.utils.ConsoleColors;

import javax.sound.midi.*;

public class WelcomeScreen extends Screen {

    @Override
    public void show() {
        System.out.println(ConsoleColors.ANSI_CLEAR);

        System.out.printf("%s%sDocRob Presents...%s\n", ConsoleColors.ANSI_BG_BLACK, ConsoleColors.ANSI_FG_GREEN, ConsoleColors.ANSI_RESET);
