It's tiny, just 5KB, so I doubt storage is the problem. Sorry, I'm really not sure what causes that issue :(
I believe that it happens because he changed the settings, because I had first played the game without changing the settings, and it worked, but if I changed the settings and pressed continue (it's the same, right?) it crashed. I then changed the settings back and it worked again.
This is just my guess, I'm no coder.
