My app is made on MIT App inventor which is an app that helps you learn block based coding. Live debugging is  when you make a change it will almost immediately change to what you did.  My Multi-App is called a multi-app because it has 6 different games in one app. My apps are Digital Doodle, Hello Codi,Talk To Me, Ball Bounce, Paint Pot, and My custom game Castle warfare. The Challenges I have faced was every thing. My Dream project is to make my own first person shooter game with 3D objects and make it a multiplayer game.
