I've placed the source code for the game on GitHub in the lauweijie/nm2207-game repo.

To build the game, bower and gulp are required. They can be installed globally with npm.

$ sudo npm install -g bower gulp

To build the game, install the dependencies and run gulp to start the server.

$ npm install --dev && bower install
$ gulp

Instructions for building the game locally can also be found in the file.
