    E) CSS Files and Structure - top

    The game use two CSS files. The first one is a generic reset file. Many browser interpret the default behavior of html elements differently. By using a general reset CSS file, we can work round this. Keep in mind, that these values might be overridden somewhere else in the file.

    The second file contains all of the specific stylings for the canvas and some hack to be fully compatible with all most popular mobile devices

    3. CreateJs is a suite of modular libraries and tools which work together to enable rich interactive content on open web technologies via HTML5.
    4. Howler is a javascript Audio library.

    Resuming, the complete game flow is the following:

    1. The index.html file calls the CMain.js file after ready event is called
    2. The main class calls CPreloader.js to init preloader text and start sprite loading
    3. When all sprites contained in "/sprites" and "/sounds" folder are loaded, the main class removes the preloader and calls the CMenu.js file that shows the main menu
    4. If the user click the Play button in main menu, the CLevelMenu for level selection is shown
    5. After level selection, the CGame.js class is called and game starts
    6. If the user click on the exit button in the down-right corner, the game returns to the menu screen
