So uh, first of all let me just say this. Absolute banger of a game. Had a blast playing through the story. 10/10. Eagerly waiting for the next updates. But the current problem I have been facing is.. The first few days when i played the game, everything was fine but after i opened the game after a few days again, it showed some error saying i couldn't save or save was not permitted. I tried running it on administrator but the problem persisted. 

so uh, i figured it out. i had my game folder attribute set to hidden (for obvious reasons) which is why it wasnt able to create new save files i am guessing, as it would create a file which wouldn't have the hidden attribute. So it's all good now. Just waiting on that sweet threesome update. Best wishes.
