Quack Attack!

You are working the duck stall at a carnival, and the ducks are not making it easy. Tap to fire; let three of them cross the stage and the round is over. New kinds keep joining the parade — fast, armoured, camouflaged, flying, tiny and tough — and each one takes a different amount of lead. Coins you earn buy four weapons in the shop: revolver, shotgun, rifle and sniper, trading fire rate for damage.
