I'm sorry you seem to have issues with the game. Can you tell me how much RAM you have and what processor you have? This seems like the game might be too much for your computer to handle. Also, when does it crash? Are you designing clothes, or reading the story?
I will try and see what I can do about an autosave, but I cannot autosave while you're designing clothing, that's not possible. I would only be able to autosave whilst you're in the menu, or reading the story.
At the moment, I can only tell you to not have any other programs running in the background as you play Tailor Tales, especially not having a browser open or anything, as that takes a lot of memory.
