I like Cracked up the most.
I found it got easier after practicing on level3.
some hints:
Do not shoot under the eggs, but shoot ahead of the eggs and they will bounce into your string,
Predict where the eggs will land and make sure you are not in there path.
When you break an egg they split upward, thus if you are close to the egg and under it, sometimes you are safe to break it,
get the smallest eggs before breaking the Largest eggs, this prevents it form getting too busy.
Level9 on the second game is Difficult
on the Second and THird game the level repeat on Level13 but the eggs now get smaller. and smaller eggs have more points. It is not hard to double your score within only a few levels.
always go for the sandwitch unless you already have them full.
I always avoid the Chili pepper since it usually makes me move too quick to avoid eggs.
If the game gets choppy it is usually because your CPU load is too high, try closing unneeded Taskbar applicaiton that may be running (on Windows) also when the game is choppy it does not paused (the choppyness is only in the display) so since the game continues to play if you can predict the movements well enough you may be able to avoid dying.
Good Luck
