FORBIDDEN JUNGLE in tin

Low on fuel, your rocket's guidance system leads you to a mysterious, abandoned spaceport on a remote moon. The spacecraft is completely overgrown by the jungle and is infested with a colony of spider-like aliens who don't take kindly to their nest being invaded. It soon becomes clear why the port was abandoned as whole sections of the station begin dropping into sinkholes! Your only hope of escape is to put a transportation portal back in service. Perhaps it will take you to the planet below? Unfortunately, all of the portals are overgrown and without power. Can you power up a portal and make your escape before it's too late?
