LOL I guess I'm in the minority who actually loves Cracking Up. I'll actually go play it if I have free time. I know tips for the game have been posted elsewhere, but I couldn't find them off hand. Here are a few things I do that help:
Watch for the bouncing pattern of the eggs. They almost always bounce in the same spot each time (it varies each level). Get familiar with the rhythm. Once you crack an egg though, the pattern changes to a new one, but the other eggs stay in their original patterns until they are cracked.
Focus on 1 egg at a time. Crack it, crack it again, and again until it's gone. When there are small and large eggs together, I do all the smaller eggs first, then work on the larger ones.
Stay a little "ahead" of the eggs coming toward you if you can. You don't have to be right underneath them to shoot at them. Shoot your rope thingy and then move to the other side of it, so that it's in between you and the eggs. That way they'll have to hit it before they can get near you.
If you can get a grapple hook or a hour glass, get it quick. I almost never get the clock or chili pepper. Going too fast messes me up, and I've never had a time issue. Until you get used to it, you might want to get the clock if it falls. Of course get the sandwiches, you'll need the extra lives, I always do.
When you get the hour glass, get underneath the eggs and shoot them rapidly to get as many from that one egg at once, then move on to the next egg. I try to get all the medium or small ones before the large like at normal speed.
If you get the grapple, move so that all the eggs are on one side of you, then shoot your rope and get on the other side of it, so the eggs can't get you. The rope will stick until an egg hits it (or after a few seconds). Then shoot again right away. Keep your rope between you and the eggs. When you get to the wall or there's no more room, then run under the eggs and go the other way and do the same thing.
Hope that helps!
