Keeper

Keeper is a calm, handcrafted puzzle game about a lighthouse keeper and forty nights at sea.

Turn the lamp. Flip the old mirror-buoys. Bend the beam across the bay until every little fishing boat is lit, then watch them follow your light home, one by one.

What's inside

• 40 nights of hand-checked puzzles across four chapters and four seasons
• First Light (autumn): mirrors, rocks and the basics of bending light
• The Reef (fog): spare buoys to drop anywhere, and coral the boats can't cross
• Glass & Fire (winter): relay lanterns and splitting glass
• The Storm (spring gales): amber and teal signal glass, so each fleet follows only its own colour
• A short logbook story that unfolds one page per night
• Par for every night, and a gold lamp when you match it
• Undo, reset and a hint button. No timers, no lives
• Night-time piano, sea, wind, rain and foghorn, all made in the browser
• Mouse, keyboard or touch. Progress saves automatically
