I remember that fun little pac man game. Your pac bug is very cute. You did a good job of making the balls.
Suggested improvements..... The cloning of the grass and wall areas need some attention because it is too obvious. Good cloning should be almost invisible.
That area where you cut the wall back looks like you cloned from the left wall. I suggest you clone from the right wall of the source image because the cloned lines still need to be vertical not diagonal.
