Why on earth would you want to cheat to complete a game? Doesn't that defeat the purpose?
I suppose we can leave this thread open, should anyone have any answers, but please be aware that this forum frowns heavily on mechanisms to defeat in-app purchases. I'm not suggesting that OP is looking for this information. I'm just re-iterating our rules, that would require closing the thread if that's the way things go. I seem to remember reading that certain mechanisms, such as speeding up the clock, or taking advantage of glitches can result in you being banned from the game. Not an ideal result.
So, gamers, how do you dump the bits you don't like, without getting into strife?
