Find the exit through the maze using the compass at the top of the screen. Move using the arrow and WASD keys. After reaching the exit you can try again with a new maze.



Although it looks 3D, the raycasting technique used by Wolfenstein 3D is actually a clever way of rendering a 2D world. It 'fakes' a 3D perspective by rendering columns of pixels with varying heights, based on the distance of the wall to the player. The world itself is a 2D grid with cells, with each cell containing information about whether a cell is empty, solid or contains a prop (a vase or exit sign). The only difference between walls and props is that a prop has a distance based on its own origin to the player, regardless of the texture column being drawn. For more information about this render technique and its underlying mathematics, see this explanation.
