For those of you who want to do more with this project, there are still plenty of things you can do, especially after finishing the rest of this book. Here are some ideas to get you thinking:
Add additional trees and textures to make the level appear even more realistic.
Right now, the player can go down into the water and get stuck. Add a new trigger, so that whenever the player hits it, it will reset his/her position back to the starting position.
Have someone play your game and see if they can navigate your environment to where you want to lead them.
Once you learn how to create encounters, add some additional combat experiences in this level.
Create collectibles that the player can collect in the level, in the same manner as the platformer project we did in Chapter 3, Side-scrolling Platformer, to reward the player travelling the map. Adding a light can help players know where to travel.
