Love the game BUT it freezes and is soo slow!!

I had the free version of the game and loved it so I wanted to get the upgraded one. I have the iPhone 4 and it would open up and let me play for a little then quit everytime! They just came out with an upgrade and it hasnt quit YET but its soo slow! And it doesnt always respond when I click something. Its very annoying. I hope they fix it again!

Teerish about Gourmania, v1.2
