Double click the flag. Use the arrow keys to move. Shoot zombies to prevent them from killing you and to get coins. Press e to pick up a medkit. if you have a medkit, press H to heal. There is a auto target feature but if you use it your score wont go up and you wont get coins.
This is not done yet. I am going to add ways for you to spend your coins, new weapons, and more enemies. Credits to Fatcat450 for the OG idea Update 1: Added WASD movement and new blaster Update 2: Added music/sounds. Thanks @Midrule_Triforce and @CitrusBadger and @FavStartz for it
