A two-dimensional game of Alien Invasion, featuring my dog Max as the defender of the galaxy! When the game begins, a fleet of aliens fills the sky and moves across and down the screen. The player's goal is to shoot and destroy the aliens. If the player shoots all of the aliens, a new fleet appears that moves faster than the previous fleet.

- Python3
- Pygame package
- Run the alieninvasion.py file in a Python IDE
- Use the arrow keys to move Max left and right, and the space bar to shoot bullets.
- The current high score is displayed at the top center, the running score is displayed in the upper right, and the current level is displayed below the running score. (The higher the level, the greater the speed!)
- If any alien hits Max or reaches the bottom of the screen, Max loses a life. If Max loses 3 lives, the game ends :'(
