This blogpost is old and the EC2 instance is not there anymore. I guess this was posted to give attention to the code.

...which is available here: https://github.com/robashton/HoverBattles

I just downloaded it and am gonna see if I can get it to run...

Edit: to run the game, download the code, and open the folder in your terminal, and run:

> npm install > npm install socket.io > mv config/keys.json.example config/keys.json > node server.js

Then open your browser and navigate to http://localhost:8000

Yeah, that's pretty much it - I don't really want to keep dozens of domain names and DNS entries for pet projects lying around when they're only going to get 10 hits a day and the code is all available :-)
