What framework are you going to use for LD23? Why not try Pixelizer?
Pixelizer is an AS3 entity and component based game framework and today I pushed version 0.4.2. This version holds mostly fixes and tweaks to the 0.4.0 version, but a few new things as well, e.g. visualising colliders.
In order to make it easy and fast to use I’ve written a lot of components already so it should be super easy to get started. The whole thing also comes with a lot of examples that show you how to work with components. Read all about Pixelizer here.
I’ll also take the opportunity to say that Pixelizer is now on GitHub. Join the fun!
