From the TempaLabs blog: "A short while after we developing and playtesting Siege!, it’s come to our mind that it play so well, it even can pass as a native mobile games experience (although with performance limitation on user mobile browser). We thought about it long and hard, and decide that it might be good to try to develop Siege! into mobile games instead.
One thing though, we already knee deep in development & testing process that it seems hard to abandon the HTML5 code to rebuild the games using different tool for mobile version. That’s when we read Richard Davey’s tweet about Cocoon Phaser Template."
This is an interesting look at using Cocoon.io with Phaser.
