I've been updating my base projects in-line with ECMA2015 standard. There is a lot of good stuff I really enjoy in this. I think the use of classes really makes code more easy on the eyes and easier to manager. I've created a base project using the Basic Game example tutorial using some of the new stuff.

I've not setup the menu or gameover states, but that should be simple enough. Hope you guys get some use out of it.
