About operation:
The operation is very simple, just press or release :)
When you press the left mouse button, the speed of time will slow down, which means everything running in the game will slow down
You can use this time to avoid obstacles and plan the next direction of movement; time will return to normal when you release the button
The ball will also move in the direction you are pointing
About the level:
Levels are theoretically combined randomly, and you can keep playing
The difficulty also gradually increases, and the bullet speed will become faster and faster
