From Ninja Kiwi:
The moon is inhabited by happy rosy-cheeked blob-things called Maro, who love to play Forehead Catch and gorge themselves on snacks. But oh no! Here comes a barrage of heavy consumer goods from Earth, goods which are not edible and tend to flatten the poor Maro if they don't get out of the way, which they are not nearly smart enough to do. Enter youin the role of a jet-pack-equipped robot shepherd with a crazed look in your eye and a big shovel in your twitchy metal fists. Your job is to batter to smithereens all the falling television sets, phonographs, and other blunt objects before they can crush the helpless moon blobs. Your secondary job is to allow foodstuffs to reach the hungry Maro, so that they can eat and grow. When they reach a certain size, a ramp will whisk them away and you move on to the next level of carnage. To recapif it's not food, break it. If it is food, don't.
