Control the character on the left to move up and down, adjust its position, and fire bullets. The goal is to aim and hit the moving character on the right, accumulating points with each hit. The game has a time limit, and the core gameplay is to kill as many characters on the right as possible within the allotted time. The more characters on the right you hit, the higher your score. Hand-eye coordination and quick reflexes will help you easily boost your score, making the game both stress-relieving and challenging.
