this was one of the first IFs I've played when I was exploring the genre a few months. Returning to mention how this is one of the IFs I've enjoyed the most!! I really like exploring the dynamic w your twin and the way it interplays w the ROs in addition to the MCs personality.
ohhh personally I just look through the twine tags but here is a collection I found of Interactive Fictions here in itch
To get you started, the (what I'd consider) holy trinity of IFs in itch are: Scout, Wayfarer, and A Tale of Crowns (I'd also add Misplaced here but it's less known afaik). Unfortunately, they're all still ongoing.
It's really hard to find complete IFs here but the ones I've found so far that I also enjoyed are:
Plunder that Booty (free)
happy to help!! yes, finding the gems can be a little tricky but so so worth it 🫶🫶
don't forget to leave ratings, reviews, and comments (even one-sentence 'no thoughts head empty but greatly enjoyed') to the ones you were able to try!! it really means a lot w making these indie dev's work more visible and sometimes they reply back to u and that interaction always makes my day
I may also recommend When twilight strikes. One of my favorites tbh, it has 12 chapters atm and is ongoing, then there's also Superstition which has two or three completed Ifs but ones still ongoing but is not being worked on for now since it's getting rewritten from S1. I could recommend a lot more but almost all of them are ongoing.
