In Natural Selection, You must catch your prey to win! You are a spider in this game. Your objective is to make it around the obstacles and catch the flies for dinner. You must use your mouse to aim, and left-click the button to shoot out your web. Your web will stick to walls and pull you along. Make it to your prey and catch them as quickly as possible! You have a timer in the top left part of your screen. Try to catch your prey in the least amount of time possible. Each level will get harder, and more flies will be added. Have fun and good luck!
