Use the Arrow keys to move the beetle Forward or rotate Left/Right/Halfway around. Click a wall to cycle it from gray, black, and white, hold space while clicking to cycle backwards. Drag the extra boxes on the left to any square to mark locations such as keys or doors. Use WASD to shift the entire maze around.
Originally made for help with the KTANE module Echolocation before it got nerfed from a 6x6 to a 4x4 maze (hence the 11x11 size).
