Control the shark to eat all the fish, octopuses and diver you can.
Each level has a star fish, which subtracts 2 points from the counter. The rest of the fish only have 1 left.
The divers will take a life from you if you hit them with their arrows. If you eat it, subtract 3 points on the counter.
Underwater bombs will take a life if you are too close when they explode, or collide with them. You can only lose one life per level.
Each new level increases the amount of bombs and diver that appear, (Up to a certain limit).
To pass each level you have to eat as many fish as the marker sets before the time runs out.
For each octopus you eat, the timer will add 10s.
You can control the shark in 2 ways, with an on-screen joystick, or by using the accelerometer (by moving your phone).
