Oxxonian

Oxxonian’s people are under attack from the super-villain Zargo. Using a
Transnuclear Hypernipple device he beams some fearsome enemies from a parallel
dimension, who can see thorough his plan to wreck life as the Oxxonians know
it – making them unable to eat their staple food, popcorn gateaus.

In order to fix the situation, the player has to explore mazes, shoot enemies
and find food, new weapons, money and tools. Badly all these things are hidden
in boxes, of which there are several types. Opening boxes is not very easy:
only if three boxes of one kind are standing beside each other, they open. The
player can push and pull boxes (like Sokoban).

Energy is decreasing constantly and therefore a constant time pressure is on
the player.
