You are exploring the Moon when suddenly.. you find a cave. Since its too big you go in with a mini-spaceship but then THE ENTRANCE CLOSES! You must find an exit to escape the cave without exploding! Use up arrow or W to go up the screen. The Spaceship HP is up there. See it? (After arriving the green line you have won.(The green line takes away 1 life.So if you have 1 life and still manage to reach the green line....You lost actually.))
