Awesome. Now someone needs to combine it with websockets/node.js (or similar) so I can see the other players on the same page!
And the HN article, if you want to drum up some more players: http://news.ycombinator.com/item?id=1738543
I hacked together a very (very) basic multiplayer with a paper-thin node.js server in coffeescript.
Yes, really: http://github.com/cushman/asteroids.js
It might deserve a newspost of its own, but I'd like to have a working server running so people can actually, you know, use it. Unfortunately, I haven't thought to get node running on my VPS before now, and it's almost 02:00 here...
Maybe something like Twitter, where new stuff to shoot appears on a constant basis?
