Alien Invaders

For Hank_Jaffe's Python Level 1 Master Project, they made a game where you have to fight off aliens for as long as you can! Alien's appear in waves of 10, and your character will always shoot. You move with the arrow keys to try and shoot the aliens down. But, if you get hit by one of the alien's bullets, all the aliens come back! As soon as you destroy all the aliens, the next wave comes, so see how long you can play!
