First gaming console? To add a game, first you need to go to their project. You will then backpack it. After, go to this project, click 'See inside' and then go to the sprite called 'game'. Then, drag your code from your backpack and put it in here. To make your own code, and publish it, you create a new project. Then, publish it, add it to the thread, and your game has been made!
