Warning about slowing down iPad need to be addressed.

I LOVE this game and continue to play although the slowdown worry that Apple cautions about. It would highly recommend to you. To correct this immediately it likely will cost you some players.
There are certain games I chose to pay that require purchases of items to make the game exciting. I agree that the cost is over the top as it shouldnt take $50 to get 1500 diamonds! I do purchase the diamond packs but I use them frugally. It would be nice to earn MORE diamonds with in the game play. Exchanging gold bricks with diamonds would be really cool as well as allowing people who cannot afford to buy power ups to enjoy this game.
My iPad is for enjoyment, games, reading and writing things. I do not use it in a business sense as I am disabled, but the iPad provides me with great hours of fun.
I do hope you will consider my ideas and correct the slowdown of the iPad itself just because of your game. Seriously, I want to recommend this game to my friends but most work and the slowdown might be a problem. Until that as well as earning diamonds along with gold bricks while running, I am forced to enjoy the game by myself.
Other than that, great game.

Ps. A strategy guide or instruction section would help too.
