Zombie Collector

You are an archer and need to survive the apocalypse.  The gameplay is simple just move around with WASD or Arrow Keys and Left Click to shoot where your mouse is.  As you take out enemies there will be chests that spawn for you to collect.  In the chest minigame you can only move side to side and have to collect 3 keys to unlock the chest, if you get hit by an arrow you fail to open the chest.  Survive for as long as possible and make it to the highest level you can.
