Players are thrown into a state of confusion as multiple characters meld together to form a gaping void in the environment, which they must navigate and solve. Movement and control are controlled by simply clicking the mouse to set positions and directions.
At the core of the gameplay are interconnected cubes and lines, which players can rotate and arrange in a space to shape the area. Intersections of cubes create new paths, bringing new areas of the puzzle into play, while separating cubes forces the player to rethink strategies.
The objective is to close the holes left in the environment, with each path correction contributing to the stability of the area. The game operates in a web-based environment, accessible in a single click without the need for downloading or registration, allowing players to dive in and out as they see fit.
