Start with the smallest animal. Move around the map using your mouse. If you see any enemies with a red outlining, avoid them, because they can take you out. Find berries and other foods to gain xp, and to evolve into the next type of animal.

There are 5 different parts of the map, and every animal is better at one part of the map. For example, water animals are better in the rivers, and move faster in water. Choose what type of animal you want, and from what map type.
