Phones and computers

Lighthouse Nights is a survival defense game that plays in the browser on phones, tablets and computers, for one player.

By night, hold to light the lighthouse lamp and aim its beam at fog creatures drifting toward the door. By day, share twelve hours between mending the door, gathering oil and searching the shore, but oil also fuels the lamp and buys lens parts. Dawn after the twelfth night wins; a broken door ends the run.

Tips

Let go of the lamp between creatures. Oil burned at night is oil you cannot trade the next day, and each lens part costs 20 oil.
Searching the shore pays on a schedule: a lens part for every 7 hours searched and a helper for every 21, and the hours carry over between days.
From night 8, shades stay invisible until the beam or the lamp's glow touches them, so sweep the dark edge rather than waiting to see them.

What do the four helpers do?

Each one turns up through searching the shore, and which you get is luck. The Mender patches the door a little each night, the Oiler saves a fifth of the oil, the Lookout slows creatures while they are still far out, and the Cat makes the lamp burn brighter.

What ends a run?

A broken door. Every creature that reaches it knocks points off, and the door starts at 100. Mending by day restores 8 points an hour, so each morning the question is how many of the twelve hours the door needs against gathering oil and searching the shore.
