me neither... only thing that stops me is the recharge on the matches..
I played it for a bit, around ~80 matches. I just ended up getting pissed off from other people getting incredibly lucky. Getting 2-3 hearts each battle, along with sling mud and the coach on me. Maybe I am missing something, but it has been more frustrating than fun the further I got into it.
Jetpack Joyride on the other hand... 20 hours so far and counting.
