Plus it's not just a port, but also a detailed series on how it was done.
Oh yeah, and you also download the source too.
And we're not talking just IE or desktops either...
Note: this game has been tested with success under IE9/10, Chrome, Firefox 6+, Opera 11+, IE9 on WP7 Mango and iPad 2. The text elements are not displayed under Opera as there is a bug with EaselJS on this topic. At last, if you really want to play to the game, an hardware accelerated browser is highly recommended. I’ve got 60 FPS in these conditions on my Sony Vaio Z13.
At the end of this article, you’ll find the complete non-minified source code of this game inside a ZIP archive to download.

If you’d like to know more about this HTML5 Audio tag codecs story, I recommend you having a look to my colleague’s article: 5 Things You Need to Know to Start Using Video and Audio Today
Then, I’m downloading either the MP3 or OGG version using the following code:
Though if you're using IE9, there's added stuff just for you...
Here's some snips from the source;
