Attack on Pirate Island - Beta

Survive as many rounds as possible on a collection of islands. Round one has five enemies, and two more get added each round. Health (Green Boxes) respawns each round in set locations, and Ammo (Purple Cylinders) has a chance to be dropped by enemies when you will them. You have a selection of two weapons, a Pistol and an Assault Rifle. Switch weapons by using "1" and "2".  Survive for as long as possible and have fun. Feedback is greatly appreciated.
