If you are of the adventurous sort, try expanding your project to add the following features:
Either add the property drawers or even a complete custom editor for the dialogues in the conversation system covered in Chapter 5, NPCs and Interactions.
Extend the
Enemyclasses in Chapter 9, Getting Ready to Fight, to better configure them in the editor.Build your menus either in a single scene or multiple ones. Manage the transition between each menu state/view.
Take one of your own game ideas and plan the flow of the game from end to end using a Mindmap tool. Go beyond just the menu and sketch out the entire game.
