Cool stats for Terry Cavanagh's game Super Hexagon. I love this game and you should love it too. Try the Flash version so you know how awesome it is (Super Hexagon is even better).
Website is live on superhexagonstats.herokuapp.com. If you have any ideas for new features, just create a new issue.
Would it be possible to do something like this for another Steam game (or all other Steam games) with a leaderboard?
Yes, but I don't want to simply because Valve now knows that e.g. group leaderboards are useful (thanks, greuben :)) so I hope they will implement it as a native Steam feature. Or it may be available on awesome sAPI in the future, I don't know.
I have no idea. If there are any problems, create a new issue or make a pull request with a fix.
Oh, also buy our game Euro Truck Simulator 2. It's required to use Super Hexagon stats... Ok, just kidding. But try it.
This site was built with AngularJS. It's my first project in it, so it may be ugly. I'm using Ruby for server stuff (specifically Sinatra), MongoDB (MongoLab) for the database, CoffeeScript, and Twitter Bootstrap because you wouldn't want to look at the website if it was designed by me.
- You definitely want to get RVM (Ruby Version Manager). Life would be hard without this awesome tool. Or try pik if you are on Windows, but I haven't tried that so it's possible that it doesn't work.
 - Go to the directory and run 
bundle installin the terminal. - Open file 
env_variables.rb.example, rename it toenv_variables.rband change it to your needs (used in development, use e.g. Heroku config in production). - Run 
rake hex:update_datato update leaderboard and users. It will take a while, Steam API is slow. - Install Node.js and then 
sudo npm install -g coffee-scriptto install CoffeeScript compiler. - Run 
rake js:compileto compile CoffeeScript files in thecoffescriptsdirectory. It's a good idea to put it in a shell script before launching the server (or if you use RubyMine, just set Run Rake task js:compile in the Before launch option). - Run Super Hexagon stats with 
thin start,rackupor however you want! 
Enjoy!
