Chiming in to shamelessly plug a demo app built around StageXL: http://rockdot.sounddesignz.com/template/

Feats: Responsive Layout, Canvas2D fallback for slow mobile devices, Material Design Components, Google+ and Facebook integration, Physics engine (experimental port of Box2d), Wrapper for BabylonJS, StageXL Runtime Examples: BitmapFont, DragonBones, GAF, Spine, Particle, Flump

Bonus, port of FlexBook: http://rockdot.sounddesignz.com/stagexl-commons/experimental... (no touch support, yet)

It's at v0.6, so be kind.
