Mutant Spiders

Description
Mutant Spiders is a 1-player arcade game where the player has been tasked by Planet Earth to defeat the hordes of dangerous three-legged spiders that are attacking the Off-World Colonies.
The player controls a space ship that moves horizontally at the bottom of the screen and fires vertically. The enemies fire in three separate directions as they move about. The player has limited time to defeat each alien wave. If the player is hit three times, it's game over.
