You haven't watched out in a pet shop and have been dropped in a new aquarium - full of hungry fish. However, being food is not very funny, so you've decided to resist your destiny and hold on. You can only eat fish which are smaller than you. The more fish you eat the bigger you get. The bigger you are the bigger fish you can eat (so, beware of fish bigger than you). Bonuses like cockles and mussels will let you be immortal, grow faster, slow down the time or eat any fish, but only for a while. Good fishing!
