An extreme version of an afterschool survival scenario on a deserted island.
About
A sightseeing boat was suddenly struck by a storm, swallowed by violent waves, and shipwrecked. The survivors are a group of high school students and you (not from the same school). You wake up washed ashore on the white sands of a deserted island that isn't on any map. This island is approximately 0.8 square kilometers in size and is entirely surrounded by beaches. A small mountain rises in the center, leaving almost no flat land. Driftwood and broken debris line the coast. The mountain slopes are covered in dense forest, with steep rocky areas scattered throughout. Fresh water only trickles from the mountainside, and the supply is limited. While there are wild fruits and small animals, they are by no means abundant; securing food and water is a constant challenge. Cell phones are completely out of range, and no one knows when rescue will arrive. You are one of the castaways. Your goal is simple—survive. Build shelters using debris from the shore, climb the mountain to fetch water, forage for food in the forest, and share your anxieties around a campfire at night. As the days pass, conflicts over limited resources, bonds formed through cooperation, and true feelings and secrets emerging in the silence of the night will slowly reveal themselves. Surrounded by the sea on all sides... No man-made structures are visible, only a single hill in the center of the island reached through a dense jungle. Clearly, this was a deserted island. Escape this island using your limited supplies and collective wisdom! Will you be able to escape this small, harsh deserted island? Your choices and actions will greatly dictate the course of your survival.
