Language app with angularJS

We would like you to implement a very simple pacman
The technology is AngularJS on front end, with NodeJS communication endpoint on backend, unit-testing with karma and protractor

App

A Pacman game.

No need to use any database persistence on server-side - keeping data in NodeJS memory is sufficient at the moment.

Running the app

npm start / nodemon app.js / node app.js  (The 3 options are valid)

then go to [http://localhost:3000] 

Testing the app:

npm test                            (unit tests)
protractor protractor-conf.js       (end to end tests)

Functionality:

Additonal tasks

Directory Layout(not up to date)

app.js              --> app config
package.json        --> for npm
public/             --> all of the files to be used in on the client side
