You are a wandering fish in a body of water, with no direction but to follow your instinct. Thats right, you guessed it; eat all the fish you can see without getting eaten by the lurking piranhas (those blood thirsty mothers!)
Your fish will not like getting hit by a piranha, so much so it will cause it to be in a spin... literally
Use the arrow buttons to move around the screen to eat up all the fish without dying. Once you have eaten them all, you will progress to the next level. If you stop moving, you will be asleep - this will mean the piranhas won't be able to eat you and you will be too limp to eat any fish.
Level one you will be in a river, level two the sea, and finally, level three the ocean where you will be set free!
You will have health points, current level, name of the current fish and number of fish eaten at the bottom of your screen. Good luck!
