We featured this tutorial a while ago but it was updated this week to cover the latest release of both Phaser Editor and Phaser.
The huge multi-part tutorial goes in depth about creating a simple platformer game with Phaser Editor (an IDE made especially for boost Phaser games development). It covers assets management and the built-in visual scene builder, so you can see just how easy it is to use. All of the source and assets are available to download.
