This overview of Phaser is written by Bob De Kinder of the digital agency Intracto:
"We made basic JavaScript games for our customers before but the game ideas became more complex and required a lot more coding. Basic JavaScript + canvas code became unnecessarily complex and harder to maintain. So we started looking for a framework that would help us create those same games faster and far more constructive than before.
This blogpost will show some of the basic Phaser features, which we already used in some of our online games. But take note: when reaching the end of this blogpost, we'll only have seen the tip of the iceberg of all Phaser has to offer."
