+##Here are the various functions I used for the player and enemy logic.
+##- After creating a Sprite, I set the clayer to 0 so that more than one player / enemy is created.
+##- the Sprite must be added to the sprites list
+##- instead of using class methods, I prefer to use set functions for
+##the various methods -- loop and hit.
+##- Enemies are removed when they go off screen.
