This game was made using the Phaser framework, but if you're interested in making games or mobile apps yourself, I would recommend looking at:
Phaser - a desktop and mobile HTML5 game framework
cocos2d for iPhone a free framework for creating 2D games for Apple technology (thousands of games using this framework have been approved on the App Store). Uses Objective-C on a Mac computer.
Corona® SDK a free framework (subscription required for the Pro and Enterprise versions) for creating cross-platform mobile apps writing in Lua script. Windows and Mac versions, but need a Mac to develop for iOS.
For graphics I would recommend looking at:
For music loops and stingers try:
For sound effects:
Indiesfx (most definitely)
