As previously mentioned you start off at the bottom of the food chain as a mouse, as you eat berries you gain xp to evolve into a different creatures. Friendly players/objects are indicated through a light green border than outlines the objects, dangerous players are indicated with a red border, make sure you avoid these players as a newbie! Although eating berries is the way to go for food chain progression it is also important to keep your water meter topped up through consuming the blue blobs that spawn around water spots.(Bigger blue blobs) Water is consumed slowly as you move around or more aggressively depleted through sprinting.
Player movement is controlled through mouse movement, keep in mind that your movement can be slowed or obstructed by certain objects if they’re bigger than your character. For example when you first spawn you can not eat the mushrooms or move through them so its best to go around them. Sprinting is available in game and can be used through pressing or holding in your space bar but be aware this dose consume water to use!
