Loved this visual novel but 1.12 gave me an odd sort of error (img linked) opened in notepad for some odd reason
It looks like it's downloaded to your OneDrive, so it could be that RenPy wasn't able to load a certain file due to your permissions settings or a connection error.
I wasn't able to replicate this error, but it's also possible that v1.12 wasn't uploaded to / downloaded from Itch fully.
I'll be uploading v1.13 this evening. Try downloading that to your local desktop files and let me know if the issue persists.
