To play the game, use the arrow keys on your keyboard to move around the map. Use the WASD keys to change the direction that the sun's light is coming from. You can only move if you are in the shadows, so you will need to keep moving the sun around until you have a clear path to walk on. Use the arrow keys to move and the WASD keys to change the direction of the sun's light as you navigate the map and try to find a safe path through the shadows.
