A simple Phaser.io demo using GridEngine. (https://github.com/Annoraaq/grid-engine)
Needs a webserver to run correctly.
For example, you could use https://www.npmjs.com/package/http-server installed globally: npm install --global http-server
and then run something like: $ http-server -c-1 -a 127.0.0.1 ./public
Or other options in the guide at: https://phaser.io/tutorials/getting-started-phaser3
