Can't save game when not running as Admin (Win 10 64 bit, Itch version).
If anyone has trouble saving their settings or saving the game's progress, running the app with administrator privileges might be the fix.
I usually don't encounter this sort of issue, as I run a rather lose Windows security setting, and was doubly surprised as the game was also not installed in a protected file system. But oh well. Just something to be aware of I guess.
Otherwise having a great time!
