Dead Man's Tide: Skull Rock

The 1700s. Your ship hits a reef in a storm off an uncharted island. Walk the plank off the wreck, swim for the beach and survive long enough to find a way off. Search the wreckage along the beach for an axe, flint and steel, rope and sailcloth. Chop young trees, build a shelter and a fire, make a rod, catch a fish and cook it, boil water from the stream, and sleep out the first night. Then go inland. Follow the track to the lagoon, calm the wild horse grazing there and ride it bareback up the mountain to a pirate camp. The captain's chart points to a sea cave in the north cliffs. Build a hang glider from the sailcloth, fly it off the cliff and find the sloop hidden in the grotto. The island is open. A clue trail and a goal tracker show the way, or switch the clues off and find it yourself. Your map fills in where you have walked. Built in three.js. The island, sea, sky and rock are drawn in code with CC0 textures from Poly Haven and ambientCG. The castaway was made with Meshy; the props are free models from Sketchfab and Poly Haven, credited in the game.
