This is a casual game that simulates the movement of objects in physical space. Only by adjusting the angle of the mobile phone can the two "2" on the screen coincide. With the increase of the difficulty of the different level, there will be various obstacles that can change the gravity, repulsion and rotation. The coordination ability of hands and eyes can be trained through the game. In addition to the default level in the game, players are also allowed to design and customize their own level and share it with other players after uploading.
