I had this problem, but there is something you can do!! Not sure it's legal though, and I'm not sure your sibling will like it...

Do they frown upon murder where you come from? :P

Haha, yes they do frown upon murder, interesting idea though... JK!

*sigh* Oh well that just means I can go back and get all those heart pieces I missed...

One of my siblings saved over my game, is there a way to get it back?
