May the last one to leave please turn off the light

A small game made for the Trijam #160 How long was the development time? Ok, it was a bit more than 3h. It was 5h to be specific. Why? I just had too much fun developing to stop after 3h. Sue me. Whats the goal? Turn off the lights in all the rooms, and then leave the building. Cant be too difficult now can it? How to play? Just move the character with the Arrow Keys or WASD. Use Left / Right to turn and Up to move forward.
