I have been playing CCS for a long time and love it.
I was thinking the only thing missing from this game is the ability to play with your friends live. The idea is you both have the same level and you compete to get the level out or get the highest score. Another idea is you take turns in getting a level out together. Also In vs mode you compete to get a "gold candy" out of the bottom of your screen with a mirrored level above which is you opponent's.
Anyway if you like these ideas i can discuss further
