I18n not installed

[Hettomei]

Just a comment to ask you to add in Readme :
gem install i18n

Because when i run ruby -rubygems pong.rb
I got

You don't have i18n installed in your application. Please add it to your Gemfile and run bundle install
LoadError: no such file to load -- i18n

--- not about the issue :
I would like to tell you : Perfect source to start ruby game with slick :D Thanks a lot

I made a little game using java and slick, and I pass a day long only to install it and run, but with your readme

    rbenv install jruby-1.6.5
    gem install isolate
    ruby -rubygems pong.rb

Isolate installs all dependencies automatically. This one was missing, I've fixed that, thanks!
