Destroy All Zombies

Zombies again...... They still haven't disappeared? Looks like you wasn't efficient enough. The indie-casual game of Destroy All Zombies comes to finally close this stage. Your mission is to destroy zombies that have remained hidden with the help of a slingshot. Aim well to knock down as many as possible in one throw. The magic skull will destroy them instantly, you just have to hit them. The idea seems simple, but how well will you manage?
