Pacman game -- 2

I have the pac-man and i want few things to be completed. I want the pac-man to open and close the mouth like in a normal game of pac-man. i want the ghosts to get the different images that are provided in the code. i want the pac-man to be able to pass throught the gap and come out on the otherside like a normal game of pacman. and i have some drop fps that i need to fix it. Also at the end i would like you to note what you changed so i know what you changed in the code.
