Galaxeroids is my entry to the 2017 GitHub Game Off.
It was created entirely in-browser using Glitch for code and Piskel for graphics.
You can play it here.
Thanks to Pixi.js for general rendering and animation duties and GSAP for the alien attack animations.
It reuses some original code and assets from my first attempt at a retro game Invaders from... Space!.
The app uses uncompiled ES6 (view source) so it requires a fairly modern browser. I test it (sometimes) in Chrome (Windows, Android), Firefox (Windows) and Edge.
Thanks to Classic Gaming for the sound effects!
