This is my pathfinding machine which helps the scratch cats to path find towards the apple. Press space to spawn the scratch cats. You can move the apple by dragging it around the screen, the boxes with arrow marks are the machine to help in pathfinding. While the mouse is down the boxes and arrows should appear, if not, your cat won't find the path to the apple.
