Stuck in a room with only your lamp to protect you, you must keep it going by repeatedly tapping the up arrow key. As long as the light stays on you are safe, but once it goes out all hope is gone.

White screen indicates that the lamp is currently lit.
Black screen indicates that the lamp is currently not lit.
The lamp will blink to indicate how much power is left, the faster it blinks the less power is left.

This is my entry into the 1Bit jam.
