I used to work with Stage3D when it came out. Its a crippled API with an even worse shaders API. AS3 spawned way too many OOP practices in the Flash world for my liking, it was the most naive way to code games I've seen until people started doing the same in JS. Angry Birds is so simple a game it could waste 90% of the system's resources and still run smoothly. The build pipeline for AIR is also terrible, with XML configuration and arcane documentation and plenty of non-documented behaviors. I once had to maintain a Flash extension, ExtensionBuilder is as bad as a toolchain can get. I'm so glad Flash is dead :)
