Hey! Sorry you're running into some issues! Do you have a bug report or does it just crash to your desktop? What version of Mac OS are you running? The game does autosave, by the way! They're kept under the "A" tab in the saved games menu.
i have a save right before the crash happens, you just have to choose the 'worry' option. i can probably extract the save file if that's helpful but i'm not sure where to find it
