The game is a 3D perspective breakthrough game. You can unlock it whenever you pass a level
Select an appropriate angle to launch the shell. When the shell hits the black cube in the scene and makes it contact with the ground, you can pass. Whenever you pass the level, you can unlock the memoir, which records 7 pictures. When you pass the 10th level, you can unlock all memories.
This game is very difficult. There is no accurate star prompt in the game. The fired shells will move in a parabola, and the lens will rotate when the level enters the back. You need to find the right time and launch shells accurately to pass!
