Hi WillWam

The instructions on the getting started guide didn't work for me and I had problems getting it to work.
Try cloning the example as described in the guide, but run npm-install before running npm-run - I think this pulled down some dependency that wasn't already in my environment.

What I did:

git clone https://github.com/gamestdio/colyseus-examples.git
cd colyseus-examples
npm install
npm run bundle-colyseus-client
npm install

Hope that helps,
Chris.
