In this game you are a kind of a bird moving on the ground. Different objects fall from the sky. Some of them are food and other are predators. You must eat the food to fill your energy and kill the predators. Your main objective is to stay alive for as long as possible, so you must not kill all predators, but avoid them. However, when you kill predators, you earn points, so it's worth it. Move left and right with A and D keys. Aim and shoot with your mouse. If you hold the mouse button for a while, you shoot a blood geyser instead of a normal blood ball. Blood geyser is highly destructive, but it requires a lot of energy.
