Defense Fleet

Game description:

You are going to defend your home world against those alien spacecrafts that are trying to destroy it , and you have 3 spaceships to start with , so survive the first enemy wave with at least one ship intact , and then use the points you earned from destroying enemy units and asteroids to purchase more units to strengthen your defence , don't worry , your units will get bigger and stronger when they attack enemies or asteroids and their health will recover slowly over time after receiving damage from the enemy ships , so good luck .
