Defend the solar system from an alien invasion on this modern twist on space invaders.
With two game modes four levels and a bunch of aliens to destroy, there's plenty of fun in this messy space shoot-em-up.
An entry for js13kgames. I've wanted to do something with polar coordinates since working on the ABC 2013-14 ashes catches game, so here's a little radial shooter for a bit of fun.
This project uses Gulp.
There's a couple of rerequisites that I haven't included in the Gulpfile.
- Build the SVG package.
cd src/img;noode encode.js - Build the compacted campaign files.
cd src/campaign;node jsonpact.js
You only need to build these when you change the files in the respective dirs.
npm install- Run
gulpto start up a server on localhost.
gulp buildbuilds everything into dist/ and packages Chrome Web Store and Firefox Marketplace targets into chrome.zip and firefox.zip.
The game has been tested and made to work on the major browsers.
| Browser | Support | Mobile |
|---|---|---|
| Chrome | A+ | Yes |
| Firefox | A+ | Yes |
| Safari | B | Yes |
| Android Browser 4+ | B+ | Yes |
| Internet Explorer | F | No |
There have been reports IE just displays a blank screen, but I haven't got a Windows machine or the time to debug it. The game should (eventually) work on IE 9+.
Safari on iOS is kinda slow. It's playable but visibly choppy. I'm not sure if it's slower hardware, browser or both.
The #js13k build is in a separate "js13k" branch, and includes some last-minute optimisations to bring it under the required filesize. The branch is provided as a reference only and is out of sync with master.
