Use WASD or arrow keys to avoid the colored circles. When the colored circles touch your character (the black circle). Stay away from the colored circles and try to get the highscore! Advanced Information: The colored circles gain food every frame they're touching you depending on that creature's size; bigger creatures get more food from you. Since creatures that touch you gain food the most dangerous creatures are the most likely to reproduce. Be careful out there. When not touching you, creatures normally get food from eating items around the map. (these items do not effect you): Milk carton: 3 food banana: 5 food apple: 10 food Wizard Taco: 20 food The different food amounts lead to different Eco-systems where different types of creatures evolve all around the map!
