This is a casual puzzle tower defense game. The command tower you need to protect is in the middle of the maze. You need to control the ball to hit the enemy until it is eliminated. The ground will show the enemy's route, but the game feature that the ball can only move in a straight line makes it more difficult. There will be many obstacles in the maze to help you stop your ball, but this will also greatly hinder your route. You need to develop a more reasonable route based on the obstacles in the maze until all enemies are eliminated. As the level increases, the maze becomes more complicated. The enemies are also upgraded to be more difficult to eliminate. You can use the four skills in the toolbar to complete the task. Can you protect your command tower？
