Super Obliteration

Thirty levels of boulder-blasting await in this platform shoot ’em up, which
can be thought of as Pang meets Turrican. The levels start with varying
amounts of boulders, and as soon as you shoot at one of them, it breaks up
into 2 more which are half the size. Eventually they become small enough that
they disappear.

Your character is a human sprite, so you’re bound to the ground unless you can
jump onto one of the strategically-placed ledges. There are several different
weapons available, which you don’t lose when you die.

There are numerous different control options – the standard one involves
always firing in the direction you’re aiming, but others include one where
your firing direction can be changed by flicking the joystick with fire held
down, an option where you move using the main 4 directions and use the bottom-
left and bottom-right diagonal to rotate the firing direction, and an option
where you use one joystick for direction of movement, and the other for
direction of fire.
