Either carrying egg or being capable to attack is neat idea, but it isn't finished from the level design. I managed to complete the game without throwing the egg once. In some later levels I had a feeling I was bypassing the intended part of the level. I think, if the jumping wasn't so much "jetpack-ey", it would be a lot harder to just run through the whole game with egg in the hands. A few tweaks to levels, enemies and egg-aiming, and the game can fully live to it's potential.
