* On screens where the enemies move consistently pick them all off in batches when they appear. You will then have a few seconds of clear time in which to shoot more hoppers before more enemies re-appear.
* In the caterpillar room, stay away from the edge of the screen as the enemies only move there. Once one complete a full circuit of the room, it will mutate into a butterfly which quickly homes in on you. Try not to let them complete a circuit.
* If you are about to be crushed by the walls, use a smart bomb as they are easier to obtain than extra lives. It's worth the price to save a life.
* In the bonus room, run over the higher numbers first, especially those to the left and right edges as they are quickly swallowed up by the moving walls.
* It's better to shoot the last little hopper near the top or bottom of the screen, as you then have some extra time in which to pick off a few more enemies before the walls close.
* The enemies appear opposite to your position. For example if you are at the bottom of the screen, they will appear at the top and move towards you.
* Try only to use smart bombs when the maximum number of enemies are on screen to maximise their effect and your points for doing so.
