Geehonk Caverns

You fly a gun pod inside a cavern where ice stalactites keep growing down from the ceiling, a block at a time in random columns. Touching a stalactite destroys the pod. The pod fires in the direction it faces, up, down, left or right, and a shot that hits a stalactite breaks it from that block down to its tip, for 5 points a block. Geehonks drift in from the left wall, zigzag across the cavern, bounce off the right wall and leave by the left. They cannot be shot, and touching one destroys the pod. More Geehonks appear as the score climbs, and the stalactites grow faster the more you break. Each lost pod starts a fresh cavern; the game ends when the pods are gone. Choose the level and three or six lives on the title.

Controls: Either controller: the stick flies the pod and either button fires (hold it to keep firing). On the title, up and down choose a line, left and right change the level and lives, and a button starts or shows the credits.
