A survival game set in a forest that will kill you if you stay long enough. The exit requires building a bridge over a river, which requires finding the river, which requires navigating a forest designed to disorient. While doing all of this, heat, hunger, and thirst are all declining. Craft tools by combining or cutting found items. Fill containers at the river to manage thirst. Manage warmth against the cold. Escape before the combination of needs overwhelms the ability to keep moving.
