Historical videogame that in spite of its venerable age remains fascinating due
to its simple effectiveness.
We are on an hostile planet and must mount the three parts of our little space
ship.
Then we must fill up the rocket with fuel using the boxes that go down from the
top, perhaps sent by the mother starship.
All this work must be done continually moving to avoid the contact with the
unfriendly creatures that live on the planets we explore, which become more
hostile as game goes on.
