Good game with bad programming

all records save in caches folder: ~/Library/Containers/com.rovio.mac.badpiggies/Data/Library/Caches/com.rovio.mac.badpiggies/

That’s mean:
1 You cannot backup them by TimeMachine;
2 You cannot keep them while upgrading;
3 You may lose them by running some cleanup program like cleanmymac2.

Why not to save in a normal folder or use game center instead?
