This site is truly amazing. Wonderfl is an online ActionScript compiler with an interface that encourages code-sharing. It’s an online community for ActionScript developers. The game above is as sophisticated as the old arcade game that inspired it and you can peek under the hood at the code that makes it work ( to play us the move;arrow or wasd/shot;ctrl,z,n/slow;shift,x,m). The projects on Wonderfl currently shared range from simulations, experiments to games but there’s no limit to the kinds of Flash apps that could be collaboratively developed on the site.
