Nutsimilian is a turn-based 2D tile sandbox/simulation game with an emphasis on exploration, experimentation, and creative thinking within a procedurally generated world.

The game world is divided into "pages" that the player travels between by navigating to each edge. The world is constructed of "tiles," which represent various materials and concepts laid out in a grid. The world does not update in real-time; the world only moves when the player moves. Tiles can be moved around with the mouse cursor with complete freedom.
