Underwater fishing

You have 3 lives, to capture everything you can.
Sharks will take a life from you if they bite you. You can kill them by shooting two harpoons at them.
You can control the diver in 2 ways, with an on-screen joystick or using the accelerometer.
To unlock the items in the store, you have to get them in the same game.
The prizes are the crab and the octopus, which are at the bottom, and the sea turtle and the manta ray, which are on the surface.
What level will you be able to reach?
Will you be among the best?
