Slither (Colecovision)

Your ship is surrounded by deadly snakes and dinosaurs! You can fire at your wriggling attackers, but one shot rarely does the trick. Snakes can split when your laser blast hits them. Pterodactyls menace you from the air. A tyrannosaur drops more brush to block your way. And after a few rounds of play, invisible snakes join them all to chase your ship!
