If not then, we recommend using an HTML5 game framework like Phaser or an HTML5 game development tool such as Construct 2 for you to start developing your own HTML5 games.

You can also develop games using game development tools such as Unity and GameMaker. Take a look at these Android game templates for some ready made games with source code, graphic assets and sounds that you can use to publish your own game.
