Thing is, I don't have an appdata folder in the entire VN's folder, so I'm assuming this is a thing exclusive to when you're playing it directly from the itch app, which presents a problem at the moment since the patreon build version on app seems to have not been updated since last September, and the recent Patreon builds have been folders
The appdata folder is separated from the game folder and i think it's not exclusive to the app, before i started to use it i downloaded the games directly via the site and i had an appdata folder. If i uninstall the game in my games folder, the files in the appdata folder aren't deleted, so if i re-install the game i get to keep my save files and my progression (read text), at least that how i understand it (i'm no expert hehe).
I remember buying a version of the game for like 5 dollars just before it went on hiatus last year (?), but i didn't have to buy the limited version of Lars special episode, i just downloaded it and now i wonder how could i do that if this version of the game apparently wasn't free....? And i don't remember if i downloaded it via the itch app or via the itch site but either way i got the game folder and the appdata folder so i don't know what else to say
