This is a hardcore game, and it's not the easiest control. But if you can acquire combat skills, then exciting battles with pirate ships are waiting for you. The main task is to destroy all the pirate ships that are firing guns at your ship. When the core hits the ship, one cannon is taken away from you. Hitting a ship, in the absence of guns on it, is considered a loss. A collision with a pirate ship, land or border is also considered a loss. You can increase the number of cannons and cores. To do this, collect the appropriate items from the surface of the water. Cannons and cannonballs appearing on the surface of the water have a limited life span. The lifeline for pirate ships is shown on the left side of the screen. Important: the ship has great inertia, so it takes a long time to gain speed and stop. The same applies to turns. When turning the ship in one direction and changing the direction of rotation, the ship will first slow down the angular velocity to zero, and only then begin to turn in the other direction. The value of the ship's speed and angular velocity is displayed on the screen.
