Hey there! It's already possible to download the whole folder and either play it offline in any browser or use Twine to play it!
Perhaps i'm stupid then, because i can't see a download button?
That's a heck of a leap from "I don't understand how to do this" to "I must be stupid"! It's just something you can do to all HTML pages in any browser, not a button. But I will also upload a version for downloading for you ✨.
Haha it's just a translation of something we say in my language. It roughly means that i must be overseeing something very obvious. But thank you for the download :)
