As reported by @hansrodtang (thanks!) on Gophers Slack, the following link in GopherJS README.md no longer takes you to where it used to:

Performance is quite good in most cases, see HTML5 game engine benchmark.

The link is not quite broken, but it redirects to the home page of http://www.ajhager.com/ and the enj demo is nowhere to be found there.

@ajhager, since it points to your demo on your website, can you please give an update here? Is there an updated URL we should use instead, or do you recommend we remove the link to that demo (possibly putting something else in its place)? Thanks!
