// port of the start of this tutorial:
// https://medium.com/@joseph.a.guzzardo/intro-to-phaser-for-javascript-6bf4b5a09085

// code basically unchanged - just put inside a getScript 

// did up as far as creation of player and physics
// next step would be to add the stars



// assets from:
// https://phaser.io/tutorials/making-your-first-phaser-3-game/phaser3-tutorial-src.zip
// missing - got them from Internet Archive
