Playing is very simple and you will need only mouse to play it. With moving the cursor you move your fish and with left click you are using your speed boost or walking on the island. Yes, they are island and you can even walk on them. They are helpful for hiding and looking for easy prey as well. I recommend you to be patient and collect plankton even on the third or fourth level. Move a lot that will help you find small fish that can be attacked. If some fish is trying to catch you for a long time you can swim on the top of the ocean, jump out of water and you will successfully escape them.You choose your animal and spend your time trying to eat as much food as possible, but it won't be easy the sea is a dangerous place, full of predators. While there is lots of food around, there are lots of other people all trying to eat it too so you have to hide and battle your way to a high score.Much fun! Join now!
