Use your up and down arrow keys to aim the guns at the eggs. If any eggs reach your base, your base's health is reduced. For every two broken eggs, you get one point. Try to survive as many waves of eggs as possible. You can drag your guns anywhere you want. Use space to upgrade how many guns you have, but it uses 25 points. You can have a maximum of nine guns.
I made it all myself. Any similarities to other games are entirely coincidental.
