Basically, it turns out eggs are aliens from the planet eggopolis! They came here, and since people eat so many eggs, decided to destroy humanity. You (obviously) Don't want to be destroyed, so you are shooting eggs at their ship for them to save. Have one crash into the edge, however, and you lose. Good luck!
I worked as hard as I could for more than 2 hours a day for more than a week on this. I even researched music ideas, and another day on just making it look good. Please at least give ideas about it
