VERY fun, especially for being at its core essentially a mindless top-down shooter. The different "weapons" are fun to learn and use and the controls are quite intuitive, with the possible exception of the health. Maybe you could make it so it consumes eggs as long as R is pressed, possibly with diminishing returns to discourage spamming.
As a side-note when I read the title of this game I first imagined a rush to get everything possible, sort of black friday + combat. While this might still be a worthwhile idea, I am definitely not disappointed.
Bravo, sir
