This is incredible just as a game, removed from the context of a jam.
The fact that it was made in a week is mindblowing.
My only criticism is that the egg spawning seemed like it could occasionally be a bit unfair, to the point where an entire game can be decided by where the second round of eggs spawn in a worst case scenario (which unfortunately happened to me).
Also a two player mode would be really nice, though it's understandable that would be out of the scope of a game jam.
