Spiderdroid Atari 2600

This is the future, when droids fight. You send your Spiderdroid to capture a building by covering the structure with its unbreakable Droidweb. Your Spiderdroid lays down a strand of webbing by crawling along each beam. Once you've threaded a strand of webbing completely around an opening, the Spiderdroid throws a web over that opening. Your goal is to crawl through all the beams of the building so that the entire structure is caught in your Droidweb.
