This is an entry to https://itch.io/jam/js48-1 made with Phaser. Our (me and RustiSub) submission can be found at https://itch.io/jam/js48-1/rate/39200. The design, all game-specific code and all assets were created in under 48 hours.
The code is far from clean for obvious reasons :)

You'll need node and npm to build this locally. Then:

• $ npm install in the project root
• $ gulp to make an unminified build and watch for changes
  • You can also $ gulp build to make a minified build, but you'll need to alter your index.html to load the minified file instead of the dev one.
• Fire up a web server and load the index.html in your favorite browser. file:// won't work.

As Phaser is directly loaded in the index.html you'll need to include it in one way or another if you want to release anything.

For example, the .zip we uploaded to itch.io contained:

1. the assets folder
2. the app.min.js from the build folder
3. a copy of the latest Phaser.min.js
4. an index.html loading Phaser.min.js and app.min.js

All of the amazing art and a lot of design input was done by RustiSub.
