It’s designed to be playable with screen-readers, and has been tested with ChromeVox, NVDA, and JAWS. There are a few keyboard shortcuts to make sightless play a little easier: alt+c (focus command box), alt+x (focus first of latest outputs), and tab and shift+tab to navigate the page.
I plan to make the engine open-source and also make a visual editor for the creation of new text adventures without any programming requirement. It’s technically already possible to make new games with it, but the author would have to edit JSON files by hand (or in an unrelated editor). Let me know if there’s any interest in that and I’ll work on the editor sooner than later.
Thanks for looking! Hope someone here enjoys it.
