It takes a few steps to get there but this is their own example game:

ETA:

here is a Cloak Of Darkness in Ink https://github.com/micabytes/mica-ink/blob/master/sample/clo... which can be compared to other languages http://www.firthworks.com/roger/cloak/

I'm happy to report that this Ink-based portfolio is accessible with a screen reader. I wonder if Inkle ever plans to switch to web technologies for their full-blown games, instead of embedding Ink in a game engine.

I've got one up [0] at the Spring Thing Festival of Interactive Fiction [1] that's a pretty straight-forward example of Ink.

There are lots of examples of varying complexity on GitHub: https://github.com/search?q=extension%3Aink&type=code

(A few of those are false positives because someone made a personal scripting language called Ink, but most of them appear to be the interactive fiction from this article)
