Downward Spiral, The (Public Domain) - Gameboy Color - Experimental, Adventure

The Downward Spiral is a homebrew first person shooter. Blast the alien invaders back to their home planet from the lush fields of the forest to the fiery desert of Egypt to the alien center location-Reflex Point. To move on to another level, you must succesfully kill all the aliens residing in a level. After you kill an enemy, another enemy will respawn in its place, so be alert. To kill either an Otaku or BigRedHead, line up your gun vertically with the enemy and fire your shotgun.
