All of the examples should now be run from the Phaser Examples site.
If you have PHP installed into your web server you can also access the Phaser Debug Runner.
Before it will work you must have the Phaser git repository cloned locally to a folder called 'phaser'.
This folder should sit along-side the Phaser Examples, for example:
/webroot/phaser
/webroot/phaser-examples
If your clone of phaser is in a folder named something else then please edit the config.php file accordingly.
