Hey so....I've just made my itch.io account for this game and downloaded it about a day ago, and every time when I try to save changes made or go back to previous screens the errors above keep showing up and completely freeze the game. Anybody know why such errors are occurring and how can I stop it? 

My current PC is Macbook Pro Catalina 10.15.5 newest version. Thank you. 

Better not listen to me cause I'm not sure, but I think I saw it before and the problem is cause the file is read only, there was another person with similar error, and he got his answer in this topic: https://itch.io/t/808946/problems-with-data

(But maybe better not listen to me and wait for more competent person to answer)

As explained in the topic Demnadro linked, the error message "read-only" refers to the location on your system. The game is not allowed to create save or config files in that location, as it's read-only (="write protected). Move the entire folder to a different location, which is not write protected, or change the folder settings, to solve this issue.

Will do. Thank you!
