Nothing new or original here. Your spaceship shoots at swarms of armed bats which fire back at you. Having got rid of them, you evade a surge of flying doughnut bars (that's how the bumpf describes them, anyway).

Admittedly, this game's intended for nine-year-olds: and it is pretty difficult, even at the first level. But that shouldn't trouble those of you who trained in the arcades. You use keys instead of a joystick too - makes a change.
