Try to stay alive as long as possible while deadly missiles fall from the sky and a parade of wicked monsters strut their stuff on the ground below. Unfortunately, every single missile is aimed directly at your head and you will need excellent reflexes to guide them to their targets without getting hit.
Use the arrow keys to move left or right, and press [Z] to jump. Destroy several monsters and Air Support advances to the next level of difficulty adding a new breed of monster or turning up the speed. Soon you'll find yourself in constant motion as the patterns of each monster type combine and intersect, like some unnatural living fugue, all the while avoiding the endless stream of missiles. Beautiful though that may be, I do have a small complaint: the rhythm of the missiles hiccups as each new level starts, which can seriously mess with your timing.
