At the end of the last level, Agmos had a flashback. He saw himself playing with a toy spaceship and people on the ground. Then all of a sudden, he crashes into a tree and and finds a cave... He knows that it will be dark so he made a torch and went into it. In this level, the are two different paths with different obstacles. You have to go through both paths to win. Things aren't all glorious under ground but make your way through. You can do it!
