-What does it show you about pygame?
-
-* pygame.sprite, the difference between Sprite and Group.
-* dirty rectangle optimization for processing for speed.
-* music with pygame.mixer.music, including fadeout
-* sound effects with pygame.Sound
-* event processing, keyboard handling, QUIT handling.
-* a main loop frame limited with a game clock from the pygame.time module
-* fullscreen switching.
-
-
-Controls
---------
-
-* Left and right arrows to move.
-* Space bar to shoot.
-* f key to toggle between fullscreen.
