In the new exciting online game Pulse you will have to move a black ball along the line that measures a person's bullets. In front of you on the screen you will see your ball, which will move forward and gain speed. It will move along the red line. Look at the screen carefully. On the way of the ball there will be obstacles in the form of ledges. While controlling the ball, you will have to maneuver in space and try to avoid collisions with these ledges. If the ball hits at least one of them, then you will fail the level in the Pulse game.
