Use the keyboard arrows to move Tux up to the door. Use the spacebar to switch between 2D and 3D modes. 2D mode just gives you an indication of your position, like a map. You cannot move Tux in 2D mode.
Erabili teklatuko geziak Tux ateraino eramateko. Erabili Zuriune tekla 2D eta 3D moduen artean aldatzeko. 2D moduak non zauden erakusten dizu, mapa batean bezala, baina ezin duzu Tux mugitu modu horretan.
