Do it. I've used Ink for tutorials, and it's magic. It works so well. If you add a way to update changes while the app or game is running, it makes an amazing workflow for the tutorial authors or level designers.
I had the same idea a few years ago. We had a chat-bot we used for onboarding, and I considered trying to reimplement it in Ink. Didn't get the chance in the end, but still interested in the idea.
that's a really cool idea! a few years ago I was tasked with building a simple interactive guide to help users with a specific thing (setting up 2FA on their Steam account and connecting it to our website), and it wasn't too bad to throw together a bespoke interactive guide flow thing in html/js, but yeah, you're right, Ink would make something like this very easy. will definitely tuck this idea into the back of my mind for future use, thanks!
Yeah, you can also definitely do this on "no-code wiki" platforms like notion or coda. I like these two because you can literally build a visual DB of all your references, resources, and entities (with relations, backlinks…)
Ink has its advantages, including the text format and custom logic.
Wizard/Form Builders are just too constricting, and Static Pages/Doc Generators are too loose. It looks like a good middle ground.
I'm still hesitating between different software. Ink’s Markup format seems good for editing and revision control.
