I've been working on a playable adaptation of an old Castlevania game book, using Twine. Specifically this book here:
https://castlevania.fandom.com/wiki/The_Devil_Castle_Dracula:_The_Battle_of_Old_CastleIt is essentially a choose-your-own-adventure book, but with several tabletop RPG mechanics. Such as stats, inventory, shops, health points, and rolling dice. Twine automates a lot of this, whereas with the book you would have had to keep track of everything on scratch paper.
I've recently finished what I guess you could call the initial version. The whole game is there, and everything works (barring the occasional bug I might've missed) - the big problem is that I can't read Japanese and so all of the text is just goofy machine translation lol. I guess that might make this more of a proof of concept. Currently trying to find someone who can help with translating the text, but if I can't then I'll just try to glean the meaning from the machine translation and rewrite the text myself.
In any case, if anyone would like to try it out (and possibly help with spotting bugs or other oddities), the link is below.
