For players than can run this twice a day, how about adding a sweep on 2nd run. Whatever level completed on 1st run is as far as they can sweep on 2nd run.
Wow no! =)))) CoF is great for its toughness; if you could sweep it then it’s no sense of playing the game. I mean next move could be “let’s make just 1 button – for rolling items from CoF randomly))))”
Sorry for straightness, it’s my point of view
