Well you were originally supposed to save the egg but......now you try and kill the egg as many times as possible. Yeah. I know it doesn't follow the theme. But it's not really a game so kinda the least of my concerns. Anyway.

Controls:
a, d - left / right
w/space - jump
s - drop through platform + fast fall
shift - drop through platform
arrow keys - directional attacks

Hit near the center of the egg for a sweet spot to deal more damage and knockback.
