Not worth the money

I really like this game-- Im wondering if people who say its too hard havent found the novice mode, maybe it would be better to have that as the default? Because thats where people usually start? Mostly Im irritated that I cant access any leaderboards, open feint (whatever that is...) crashes my phone and its not found on Game Center... Didnt even know that was a thing. I spent hours beating medium levels on hardcore mode and I cant even compare my scores. Its unbelievable that this isnt a free app... Sorry I paid money for it, fun game, but too many glitches to be worth it.
