I haven't touched this game in years, but IIRC you can turn the online features off from the options and/or refuse to log in.
It uses an old version of unity and it's one of a few games I made shortly after graduating, so the code is pretty bad, so I'm not sure I want to go messing about with it when I have another project I'm working hard on. Sorry.
I recently logged back in to itch because I'm thinking of releasing an alpha version of a new PC game here later this year, so idk if that caused unwind to show up in the algorithm or something.
