The game is an exploration game with a seemingly endless number of buildings floating in space as the stage, the player needs to land the scattered parts to the edge of the building, induce to the designated location, to make a sky courtyard including water and trees. Players will explore and solve puzzles in this world full of geometric lines, without any text, and will encounter a variety of visual illusions. This process requires a lot of thinking and spatial imagination, and every time a level is completed, more complex buildings and puzzles will appear.
When you push a part off a structure, it looks like it's falling toward another structure, but it's actually falling on the bottom of the same structure. Similarly, if you fall from the left side of the structure, you will land on the right side of the same structure. In other words, the space of this game is the mirror image of the same structure spread out.
