This is a bit of a Space Invaders tech demo (shock, horror), with a one key difference though ! - In this version, the game controls more than one Alien Swarm. All of which is easily managed with some of PlayBasic high level array controls. Namely the ability to pass and array handles around. So the game stores a main linked list of array handles that make up this scene. Then during each redraw, we run through the scene list and dispatch the arrays to the handler/drawing routines.
