So, You're playing the game & you're 1 move away. You can clearly see the end. The last cookie is 1 row above the "chocolate?" You've spread the jam in every square but one, That last candy heart is 1 space away from the box or w/e it goes into, etc. However, you're out of moves, so now you have spend your gold for 5 extra moves, when only one is needed, or start over & try again. I can't tell you how many times I've been "one move away." I wish there was a way I could use one of the Lollipop hammers after my last move, or "buy" just 1 more move for maybe only 2 or 3 bars. This is something that would only be used when the goal is clearly seen & accomplished with 1 extra shot. Not when you are just "close" & maybe a few more moves might help you.
By the way this option would be good on most of the games not just CCFS.
