Thanks! I'm always looking around for js game libraries/frameworks, adding another one to the list :) Anyone know of any other good ones ? So far I know of:
ImpactJS
LimeJS
CraftyJS
Cocos2D
I would suggest looking into Photonstorm's phaser. It's all in TypeScript, so you get Intellisense, and it's based on Flixel. They're getting close to 1.0. https://github.com/photonstorm/phaser
