I like the idea but the eggs seem out of place. Yes, it could be created by chicken to destroy the hero but it got rogue and now lives in an electric planet. But if instead of egg , maybe it could be ice that is similar to the meteor level but just the size of eggs like eggs (probably bigger for low skill and smaller for higher skill). Thus, if it was like this, the entirity of the screen would be cover with this projectile. The eggs would provide area denial but this change wouldn’t but it would make the game more chaotic.
Edit:Instead of eggs, it is hail.
