A single sacrifice rewrites the boundaries of the world. Two realms, separated by black and white. The character you control cannot cross that boundary. However, the boundary between the realms is not fixed. By sacrificing your character, you can shift the boundary that divides the world itself. Manipulate the boundary, create a path, and reach the goal. This is a unique 2D puzzle game that tests your creativity and logical thinking. Utilize gravity manipulation and various mechanisms to decipher the stage’s structure and discover the optimal solution. Even in situations that seem impossible at first glance, changing your perspective will reveal a new path. Furthermore, the game features a built-in level editor. You can create your own puzzle stages and use your imagination to craft new challenges. Manipulate the boundaries. Expand your imagination. And find the path to the goal.
