NPM distribution not up to date

[bfishman]

Hello!

Apparently the NPM distribution of this library doesn't quite match what's in the git repo.

I NPM'd and was having a ton of bugs. Turns out that

var GameController = exports.GameController = {

was actually just

exports.GameController = {

in the code I pulled from NPM. There may be other differences, but that was the breaking change.

Not sure if you're still maintaining this, but you may want to check the NPM version.

Nice work! Thanks!
