You are a fearless captain of a high-powered water boat. Your mission is to race through the seas and take on the enemies. But first, you will have to navigate through a dangerous path. The path is strewn with many obstacles that you must avoid. You can steer the boat using the arrow keys, and you can use the accelerometer to control the boat. You will have to keep a good balance of power and speed. If you hit an obstacle, your speed will slow down. You will also lose your steering ability. If you lose too much speed, you will be thrown off the boat. So it is important to keep a balance of power and speed.
