"Hooray, yet another HTML5 Javascript gaming framework! Not so fast, this one deserves consideration for game creation as it is very well done and has a large community of users and is frequently updated.
I've posted in the past about LimeJs which is also a good starting HTML5 gaming framework, but it has it's shortcomings. I believe most if not all of the LimeJs shortcomings are alleviated in Phaser."
