Finally my latest project Ludiculus is reaching what I could consider a beta phase:
http://www.ludiculus.com/
The home page has most of what I was expecting, an arcade section, a basic forum, an about and a small chat. All that will be improved if I'm able to drive some traffic.
The maker itself is up and running, with a 2D physics engine, canvas rendering, local storage, score board, and many many features.
The tutorial section grows slowly, as well as the online help.
Now all what remains is basically have people starting to use it!
Comments, suggestions, feedback are welcome as always, and share the news if you can

Cheers,
Alain
