A very impressive game & experience you all have created thus far. Card Hunter is created in As3, but are you using a known engine such as Starling? Or did you create your own, built off the stage3d framework? Or potentially something else entirely? Stoic, the group behind the up coming Banner Saga, are also using As3 primarily, but are also utilizing Java script through custom ANE libraries I believe. It is nice to see Flash based applications making a come back.
Card Hunter uses the regular flash display list and software renderer, largely because stage3d didn't exist when we started the project. I've experimented with moving some of the background layers over to stage3d via Starling, simply to shift some of our fill cost over to the GPU, but I hit a few early snags and moved on to other work. We might get back to it if we find we need to work on render performance, but for the moment it seems it's mostly okay.
