LD39: Running Out of Power

The zombie apocalypse is upon you. You've managed to make your way to an old abandoned lighthouse.

Outside, the wind howls as hordes of zombies make their way towards your shelter.

Your only hope is to keep the lighthouse powered until rescue arrives.

How long will you keep the power running for? Will it be enough?
