Press space to shoot fireballs and the cursor to aim! Hit enemies to gain kills, but do it fast! If an enemy gets to you and successfully attacks you, you lose a life. If you lose all 3 of your lives, you lose the game, and the enemies take over the world! However, once you reach 30 kills, the enemy forces run out and you get an upgrade!
Some ideas and tips from Jasper (DLstudent8), so thanks to them.
