My team's submission to the 2011 Global Game Jam, Silent Extinction is about preventing the extinction of the spoken language. This year's theme was 'extinction' and we wanted to do something that didn't involve dinosaurs. :)
Play description, game files and contributors can be found on the Global Game Jam website at

This is my first fully realized game. I hope you enjoy it! Give it a try and let me know what you think.
