Spiderdroid is a 1987 video game for the Atari 2600.
It is a clone of Amidar (a more popular game that was in the arcades and also for the Atari 2600) with a more futurisic setting. The object of the game is to fill in boxes that have to be made by moving by its four corners. There is similarity to Pac-Man also. Instead of ghosts, spiders chase you while you are trying to complete your task ( tribesmen and pigs are the foes in Amidar).
