Alien Sizzle is a simple game that is meant to have retro appeal. In fact, it is based on -- and the name is derived from -- an old game for the Apple ][ called "Alien Drizzle." And when you get right down to it, the premise of that game was laughably straightforward -- try to shoot down alien saucers (I refer to them as UFOs) that fly overhead by launching one missile at a time from your own ship (which was stationary), and timing it so that the missile strikes the UFO at the right moment. The game basically ran in an endless loop, and it portrayed your score in terms of the percentage of UFOs that you successfully destroyed in relation to the total number that have appeared.
