I like your concept i think its really interesting and could be really fun if developed further, it reminds me of old collectathons like slenderman. I did struggle to find anyway to regain my stamina though and i struggled to find anything in the forest it felt like i searched the whole map and couldnt find anything except 3-4 sticks. Its also a bit of a struggle to find my way back to the campsite, maybe some recognisable landmarks around the map could help with navigation?
