There's a submarine hidden in the water! It needs to be destroyed before it can launch torpedoes at our warships!
Do you have the reflexes to complete this task?

How to play:
The circle grows and shrinks, tap the screen when it intersects with the marker.
If you tap at the right moment a sonar buoy will be dropped.
If you tap too early or too soon, you will lose a life.
Each level you need to drop a certain amount of buoys.
When that amount is reached the submarine will be destroyed and you have won the level.
