We all know what jQuery is. After consulting the all-mighty search engine of theinterwebs, I figured out that howler.js is an audio library, that tween.js is alibrary for animations, and that nippleJS is a virtual joystick for mobiledevices.2 I was tripped up by 'zip.js' and 'zip-ext.js' initially, thinkingthat these are where the code is, but it didn't take long to realize that theseconstitute the zip.js library for working with ZIP files. Well, if the game codeisn't in any of those files, then it has to be inlined in a tagsomewhere. A quick grep reveals that it is, indeed, at the bottom of the page.
